A light-field display has been built using a rapidly spinning drum perforated with holes and stationary LED matrix panels behind it. Each hole reveals a different view of the rendered object, so the image changes with viewing angle and appears three-dimensional.
The prototype uses three LED panels and has an effective resolution of roughly 100 by 48 pixels per eye. Its viewing range covers only part of a full circle, but the display is already capable of running DOOM. It was built by AncientJames.
Building a mechanical 3D display was not enough; the roughly 100-by-48-pixel image also had to run DOOM. Even when the screen becomes volumetric, DOOM remains the final test.
P.A.R. is a 37×18 display made from 666 two-sided square tiles. Instead of giving every pixel its own actuator, a single robot moves behind the panel and physically flips individual tiles as needed to draw monochrome pixel art.
Artwork can be submitted through a website, and the machine reproduces it on the physical grid. The CAD models and code are open source. The project was created by Zimm.
Every time the display updates, a robot has to travel around behind the screen and physically flip the pixels one by one. Refreshing the image has become an actual mechanical chore.
FLIP Fluid is a large display that simulates moving liquid using thousands of electromechanical flip dots that physically switch between black and white. Because the pixels themselves move, the flowing image naturally produces a rippling mechanical sound instead of relying on added audio.
For EMF2026, eight panels were combined into a large installation with a joystick labeled “GRAVITY CONTROL” that changes the direction of gravity in the simulation. Creator mitxela says the large panel cost under £500, excluding donated parts and labor.
Instead of adding a speaker to make a fluid simulation sound physical, the display itself is made from thousands of moving parts. The screen has become its own sound-effects system.
OVODYO displays time by rotating two numbered 12-sided solids until the appropriate faces point upward. One indicates the hour and the other advances in five-minute intervals, with internal gearing rotating each shell around two axes.
Creator ekaggrat singh kalsi built the clock. Because the minute solid only changes every five minutes, LEDs indicate the exact minute between those steps.
Changing a clock digit now requires two polyhedra to physically tumble into new poses. Checking the time has become a tiny mechanical performance.
