Amazing 3D-printed zoetrope reveals an animated picture when illuminated

Add as a preferred source on Google

One of the endlessly fascinating aspects of 3D printing is just how adaptable it is. Some people use it to 3D print entire buildings, others to manufacture tools in outer space, and still others to produce “bio-ink,” a critical early step toward what will one day be fully 3D-printed biological organs.

Japanese media artist Akinori Goto has a slightly different idea. At the recent Spiral Independent Creators Festival in Tokyo, he showcased a 3D-printed artwork, which uses a spinning drum and a series of still images to produce a ghostly animated figure. Think of it a bit like the holographic Princess Leia in Star Wars: A New Hope and you won’t be far off the mark.

To make the dreamlike attraction — which Goto calls a “toki” — a reality, the Japanese artist created a 2D time axis following a figure through an animated sequence. This sequence was then divided into a series of still images, and arranged three dimensionally in a ring — so that spinning the 3D-printed drum, while shining a light on it, produces a hypnotic animated effect.

As modern as this execution is, however, the idea behind the concept — often called a zoetrope — actually pre-dates modern cinema. “The initial idea of a zoetrope is pretty old,” 3D-printing digital artist and animator Dieter Pilger, who has also co-created 3D-printed zoetropes such as the collaborative project Flux, tells Digital Trends. “The name more or less translates to ‘wheel of life’ in Greek, which I think describes the idea in a wonderful way.”

Goto’s creation recently claimed the Runner-up Grand Prix, as well as the popular-appeal Audience Award, at the Spiral Independent Creators Festival. Any single component of this project would have been worthy of sharing with Digital Trends readers, based on just how ornate it is.

When they’re all combined, though, the effect is so much greater than the sum of its parts, as you can see.

Yet another study says AI is bad for elections, and the rabbit hole gets worse
AI may be an election bomb waiting for someone to light the fuse
Voters cast their ballots on Election Day

Another election, another study has concluded that asking an AI chatbot for political guidance is a spectacularly bad idea. Research conducted during Hungary’s 2026 parliamentary election found that ChatGPT and Google Gemini offered not just inaccurate but also inconsistent and unreliable voting advice. The chatbots misclassified voter profiles, overlooked relevant parties, recommended parties absent from the ballot, and sometimes produced materially different answers when given the same information repeatedly.

Samsung’s humanoid robot ambitions are real, but factories come first
Samsung’s new robotics division has humanoids in its sights, although its immediate business is far more practical factory automation
Robot Touch Human Finger

Samsung wants a place in the humanoid race, but its new robotics push begins with machines built for factories rather than homes.

The CEO-led RX robotics division will initially focus on manufacturing robots. Samsung has separately identified humanoids as a priority, although it hasn’t announced a commercial model or explained where one fits into the division’s immediate plans.

The future of AI may depend on this one behind-the-scenes change
Running Claude on Android.

Whenever a new AI model arrives, it's easy to get caught up in the bells and whistles. We talk about how much smarter it is, how quickly it answers questions, or how realistic its images have become. But here's the thing: none of that matters much if the AI can't reliably work with the apps and services people use every day.

That's why an upcoming update to the Model Context Protocol (MCP) caught my attention. It isn't a new chatbot or a fancy AI model. In fact, most people will never even know it's happening. But it could quietly make the AI ecosystem a lot healthier. If you've never heard of MCP before, don't worry. Think of it as a shared language that lets AI assistants safely talk to apps like Gmail, Slack, calendars, databases, and countless other services. Instead of every company inventing its own way to make those connections, MCP gives everyone a common rulebook.
