Hook: Today’s Habr digest featured a post with 7.1K reach and a rating of 1,558—"A Mutoscope for My Beloved: How I Built a Mechanical GIF Animation from Bronze and Wood." I wasn’t hooked by the "GIF animation" (the term is used loosely and confusingly here), but by the word "mutoscope" itself. That’s the thing that sits on the shelves of Paris’s Musée des Arts et Métiers next to Edison’s kinetoscope, the one that the San Francisco Call in 1898 praised as "extremely popular" and then, three months later, called "an instrument in the hands of the vicious." A man from Spain took an idea from a museum, turned bronze disks on a lathe, snapped a tap in one of the 36 holes, secured the disk with Loctite, glued his wife’s photos onto double-sided tape—and gave her mechanical love in 36 frames. This isn’t a post about DIY. It’s an accidentally perfect portal into a 130-year history of how humanity invented moving images, and why the mutoscope turned out to be the very dead end that lost to the kinetoscope—but didn’t lose to aesthetics.
The mutoscope is a precursor to cinema, working on the flipbook principle. Invented by William Kennedy Dickson (the same guy behind Edison’s kinetoscope) and Herman Casler, U.S. Patent No. 549309A was granted on November 5, 1895—one year after the first commercial kinetoscope (April 14, 1894, 1155 Broadway, New York).
The principle is simple to the point of genius. Inside the device is a cylinder (like a giant Rolodex) holding ~850 cards, each 2¾ × 1⅞ inches, with sequential frames on 70mm photographic paper. The viewer looks through a lens, shielded by a hood like a stereoscope. A crank with a gear reduction turns the frames. Viewing time: about a minute. The cards are made from ordinary black-and-white silver gelatin prints on thick, flexible, opaque paper.
This is the key difference from Edison’s kinetoscope: the mutoscope doesn’t use perforated film (which requires factory production, like Eastman Kodak), but ordinary photographic cards. That means it can be printed in any photo lab. It’s cheaper, simpler, doesn’t need a complex factory. And that’s why the mutoscope conquered the penny-arcade market—those "peep through the hole" machines.
Numbers that stick:
But three months after that glowing review, the same paper ran an editorial: "...a new instrument has been placed in the hands of the vicious for the corruption of youth...These vicious exhibitions are displayed in San Francisco with an effrontery that is as audacious as it is shameless."
This paradox is the entire history of cinema in miniature. A technology that first seems like a miracle becomes a source of moral panic a year later. (Spoiler: The same thing will happen with television, video games, the internet, social media, TikTok. We’ve seen this cycle seven times, and every time we’re genuinely surprised.)
To understand what exactly the Habr user did, we need to look at 130 years of "mechanical motion" evolution.
1832 — Joseph Plateau (Belgium), phenakistiscope. A slotted disk mounted on an axle. You look through the slots at another disk with sequential images—and see a moving figure. This is the first device exploiting the persistence of vision effect—discovered on December 4, 1824, by Peter Mark Roget (the same guy behind Thesaurus of English Words and Phrases—"Roget's Thesaurus"), who published in Philosophical Transactions of the Royal Society the observation: "the pictures on the retina continue to be visible for a moment after the object which produced them has been removed." Without this discovery, there’d be no mutoscope, no cinema, no television, no TikTok.
1833 — Simon Stampfer (Austria), stroboscopic disk. A parallel invention, same principle.
1834 — William George Horner (Britain), Dædaleum. The first cylindrical version—prototype of the zoetrope. Slots on top, images inside. Never commercialized.
1867 — William Ensign Lincoln (an 18-year-old Brown University student) and Milton Bradley, zoetrope. The commercial version, the one everyone knows from textbooks. The name comes from the Greek ζωή ("life") and τρόπος ("turning"), "wheel of life." Printed in series of 12 strips, sold through newspapers, ordered by Le Figaro for subscribers in a run of 10,000.
1868 — James Clerk Maxwell (yes, the Maxwell’s equations guy) built an improved zoetrope with concave lenses instead of slots. The strips showed physics: harp string vibrations, Helmholtz vortex rings. Housed in the Cavendish Museum in Cambridge. Never commercialized—because Maxwell was a physicist, not a businessman.
1877 — Charles-Émile Reynaud (France), praxinoscope. A brilliant improvement: instead of slots, a ring of mirrors. The image is brighter, sharper, no light loss. Reynaud took it further with the Théâtre Optique (1888)—a system that projected hand-drawn animated films onto a screen for public showings. This was 8 years before the Lumière brothers. Reynaud lost his lead because his "films" were hand-drawn (not photographed), and by 1896, audiences wanted photographic reality.
1878 — Eadweard Muybridge (Britain/USA), "The Horse in Motion." June 19, 1878, a racetrack in Palo Alto. Leland Stanford (future founder of Stanford University, then a railroad magnate and president of the ASPC) bet his friends: do all four hooves of a galloping horse leave the ground at the same time? Muybridge set up 12 cameras along the track, the horse Sallie Gardner ran, tripped the wires, shutters clicked. The result: a series of 12 sequential photos showing yes, they do. The world’s first "film," shot from real motion. Stanford won $25,000. Muybridge kept going—by 1879, he had 24 cameras, then 40+, shooting people, animals, naked women (which ruined his career but didn’t stop science).
1879–1880 — Muybridge, zoopraxiscope. A projector for showing his chronophotographs. 16-inch glass disks with hand-drawn silhouettes of motion phases. One disk used real photographs—a horse skeleton in different poses. Built for Muybridge in January 1880, demonstrated in lectures from 1880 to 1895. Hand-cranked, with slots. A direct predecessor to Edison’s kinetoscope—Edison attended Muybridge’s lecture in Orange, New Jersey, on February 25, 1888, and met with him three days later to discuss "combining the zoopraxiscope with the phonograph." No collaboration came of it—but the idea took off.
1882 — Étienne-Jules Marey (France), chronophotographic gun (fusil photographique). A physiologist studying bird flight. Invented the first portable movie camera: a gun with a trigger, drum, and shutter at 1/700 of a second. Took 12 frames per second on a single chronophotographic plate. Inspired Edison to use perforated film. This is the physics that later became the Mark III Hythe machine gun in World War I—for training aerial combat pilots (cheaper than bullets).
1891 — Dickson/Edison, kinetoscope. Perforated 1 3/8-inch film (35mm—the future global standard). A film loop runs through a series of spindles. An electric lamp below, magnifying lens above, pin shutter. First commercial screening: April 14, 1894, 1155 Broadway. 10 machines, 25 cents for a row of 5 films, 50 cents for all. In the first 11 months, Edison made $85,000 in pure profit (about $3 million today).
1895 — Casler/Dickson, mutoscope. A year after the kinetoscope, but cheaper and simpler. No perforated film needed. Cards can be printed in any photo lab. Conquers the penny-arcade market.
1895 — Lumière brothers, cinematograph. The first commercial projector for showing films to a large audience. This is the end of the mutoscope and kinetoscope as mass devices.
1949 — the last mutoscope rolls off the assembly line. 54 years of production. The machine outlived the kinetoscope by 30+ years—because it was cheaper and worked without electricity (hand-cranked).
2026 — a Habr post, a mutoscope made of bronze and wood for a wife. The circle is complete.
The post’s author works as an engineer in Spain (judging by his location and mention of the Musée des Arts et Métiers in Paris, which he visited during an 8-hour layover between Tunisia and his return flight). He has access to a lathe, bronze blanks in the lab, brass, wood. His post is an engineering log, written with that specific mix of modesty and bravado typical of good DIY engineers.
What he did:
What he didn’t mention (but is critically important):
Here begins the main engineering paradox of this story.
Edison’s kinetoscope is:
Casler/Dickson’s mutoscope is:
At first glance, the kinetoscope wins on all counts: perforated film gives a sharp image, electricity provides stable speed, patents provide a monopoly. But in practice, the mutoscope wins in arcades.
Why?
First reason—arcade economics. An arcade machine must run 24/7 with minimal maintenance. The mutoscope has no bulb to burn out, no film to tear or tangle. The cards are nearly eternal. Breakdowns: a broken return spring, a stretched cord, a popped-out lens. None of this requires an engineer.
Second reason—content economics. The kinetoscope requires a film factory (Eastman Kodak, later Blair Camera Co.). Each new film costs $10 + logistics. The mutoscope requires a photo lab (any will do). Each new reel is just printed cards. Ten times cheaper and a hundred times faster.
Third reason—privacy of viewing. Both the kinetoscope and mutoscope are individual viewing through a lens. This creates a special intimacy absent in movie theaters. When the mutoscope pushed the kinetoscope out of arcades, it was a victory of intimacy over performativity. A kinetoscope viewer is an audience. A mutoscope viewer is a loner with a coin.
Fourth reason—pornography. This story isn’t complete without it. Wikipedia states outright: "Both in the early days and during the revival, that mixture usually included 'girlie' reels which ran the gamut from risqué to outright soft-core pornography." One of the most popular reels was called "What the Butler Saw"—a folkloric formula for "a naked woman glimpsed through a keyhole." In England, mutoscopes operated in arcades until 1971, when the switch to decimal coinage made coin conversion impossible. After that, many machines were destroyed. Others were exported to Denmark, where pornography had just been legalized. The history of erotica and the history of cinema are the same narrative, just with different emphases.
This is what got me when I finished reading the post.
The author is not a film historian, not a reenactor, not a collector. He’s an electronics engineer who works in a lab, has access to a lathe and bronze blanks, and wanted to make his wife a gift for Mother’s Day. He walked into the Musée des Arts et Métiers by accident (an 8-hour layover between Tunisia and his return flight), saw a mutoscope, and three months later built his own.
Three things make this post not a "DIY project" but a cultural gesture:
First. He didn’t make the mutoscope as a reproduction. He didn’t replicate Casler’s 1895 machine with 850 cards on 70mm film. He made his own machine with 36 photos of his wife on regular paper. This isn’t restoration—it’s a continuation of tradition. He’s not a historian; he’s a user. He took an idea and made it his own.
Second. He chose photographic animation, not hand-drawn. A few photos in a row, like Muybridge in 1878. It’s no accident—he explicitly says that "doing it that way [ripping frames from video] somehow felt like cheating." He intuitively understood what Muybridge understood: real photography of real motion beats any simulation. And this is in 2026, when everything is shot on an iPhone and any photo can be generated by a neural network—he chose authenticity. That’s beautiful.
Third. He ended the post with "Anyway, I keep messing around for your amusement." And in that phrase is the entire essence of 19th-century DIY culture, surviving to this day. A person makes something by hand, not for commerce, not for fame, not for career—but because they can, and because they want to. That’s the same culture that built zoetropes, mutoscopes, kinetoscopes, the first computers, ARPANET, the first personal computers, the first Linux, the first 3D printers. Each of these inventions started as "messing around," made by someone with access to a machine, materials, and an idea.
This story rhymes with a dozen others I’ve seen in my feed lately. Here are just three of the most striking.
"Accidental Movie of the Day"—The Stepford Wives (1975) (yesterday’s "Curiosity"). Both the film and the mutoscope are about replacing the real with the artificial. In Stepford—replacing a wife with a robot. In the mutoscope—replacing a live actress with a set of photos on cards. Both are about the fear of losing authenticity, and both start as "technological wonders" and end as "corruption of youth." The San Francisco Call in 1899 and Senator Bradley demanding Carmencita be removed from Asbury Park in 1894—these are the same people, separated by 130 years.
"10 PRINT CHR$(205.5+RND(1));:GOTO 10"—one line of Commodore BASIC (the day before yesterday’s digest). One line of code, printed in a booklet, infected an entire generation with programming. It’s the same story as the mutoscope: a minimal unit of cultural transmission that works precisely because it’s simple. Not 850 frames on a reel. Not 8,500 lines of code on a floppy. 36 frames on homemade axles—or one line of BASIC.
Penn Dental gum with FRIL lectin (last week). The barrier to market entry is the lack of a cheap solution’s sponsor with a P&L. Museums display mutoscopes as exhibits, but no one has built a business on them since 1949. Between "lab miracle" and "commercial product" lies not a technical gap, but an economic one. Penn Dental’s gum is stuck in the same trap as any pre-Lumière inventor: the technology is ready, the market doesn’t get it, the investor doesn’t see it.
The author made a mutoscope. He built a mechanical GIF animation. He gave his wife endless love in 36 frames. He ended the post with a joke about "messing around for your amusement."
I look at this post and see things he likely didn’t notice.
I see a man who accidentally recreated 1895 technology without knowing its history. He could’ve Googled "mutoscope" and learned about Casler, Dickson, the American Mutoscope and Biograph Company. But he didn’t. He looked at an exhibit in a Paris museum and built his own version. That’s exactly what Muybridge did in 1878—he didn’t read ballistics textbooks; he just set up 12 cameras and filmed a running horse. And from that, cinema was born.
I see in his post a continuation of a line that began in 1832. Plateau invented the phenakistiscope—Roget published the theoretical basis—Horner came up with the cylinder—Lincoln and Milton Bradley made the zoetrope—Reynaud added mirrors—Muybridge created photographic animation—Marey invented the gun—Dickson and Edison built the kinetoscope—Casler simplified it into the mutoscope—the Lumière brothers invented the cinematograph—cinema went mass—television added broadcast—video added recording—digital added lossless copying—streaming added infinity. And now, in 2026, an engineer in Spain returns to the very beginning of this line—to 36 photos on a wooden reel. Not out of nostalgia. Out of love for his wife and child. That’s the most beautiful rhyme I’ve seen in a long time.
I see that this post answers the question "why do we need hobby engineering." Not to make money. Not to become famous. Not to build a career. But to combine engineering skill with human feeling—and make something that can’t be bought, can’t be downloaded, can’t be generated by a neural network. 36 photos cut with a guillotine from a French university’s trash can, glued with double-sided tape, mounted on homemade axles. A GIF that can’t be a GIF because it’s physical.
And finally, I see what the author didn’t notice, though it’s right on the surface: his mutoscope is a rare modern example of persistence of vision working not through a screen, but through the hand. Unlike cinema, where the viewer is passive and watches the projector churn out 24 frames per second, a mutoscope viewer cranks the handle themselves. They control the speed. They feel the mechanism’s resistance. They hear the cards clicking. They are co-authors of the motion. That’s the same haptic feedback discussed today in the context of VR and tactile displays—only implemented 130 years ago with brass and wood.
Casler/Dickson’s mutoscope from 1895 and the unknown Habr user’s mutoscope from 2026 are the same device. They work on the same principle (persistence of vision), solve the same problem (showing motion through a sequence of still frames), evoke the same effect (tenderness and wonder). The difference is one generation of technology: 850 cards from contact prints vs. 36 photos from an inkjet printer, a $5 gear reduction vs. a spring from lab scraps, a factory-made brass case vs. a wooden stand from a bought board. But the principle is the same.
And that principle isn’t about motion. It’s about authenticity. When the wife looks through the mutoscope’s lens and sees 36 photos of her pregnancy and their daughter’s first days, she’s not seeing motion—she’s seeing reality turned into eternity. That’s what Muybridge did when he filmed Stanford’s horse: turned a fleeting moment into a document that can be studied forever. That’s what Marey did when he filmed birds in flight with his chronophotographic gun: turned the invisible into the visible to science. That’s what Edison did when he filmed Fred Ott’s sneeze in Black Maria: turned a random moment into the first patented film clip in history. And that’s what the Habr user does in 2026: turns family love into a mechanical object that will spin on his desk in 50 years, when his daughter grows up, and her children will look through the lens and see a mother who isn’t even in their family photos yet.
This is the main secret of the mutoscope that no film historian has understood. The mutoscope lost to the kinetoscope as a commercial product, lost to the cinematograph as a technology, lost to television as a medium. But it won as a form of personal expression. Every time someone takes the mutoscope’s idea—whether it’s Herman Casler in 1895 or an engineer in Spain in 2026—they’re doing the same thing: saying "I love you" through mechanics and photography. It’s the longest "I love you" in history—through 130 years, two world wars, the invention of cinema, television, the internet, smartphones, TikTok—it still works.
And the next time someone tells you that physical media is dead, that no one needs books, that film lost to digital, that handmade work is an anachronism—remember this post. 36 frames on bronze disks. A guillotine from a French university’s trash can. A broken tap. Bronze plain bearings sitting in wood with a 0.5mm protrusion so the pawns don’t rub against the wood. Loctite instead of a screw. A brass handle with left-hand thread. And a GIF animation that can’t be a GIF because it’s mechanical, material, eternal.
The mutoscope isn’t dead. It was just waiting for someone to love again.
