Cube made of 512 LEDs does glasses-free 3D for real (video)
No goofy active shutter glasses, no headache-inducing parallax barrier screens, no optical trickery here. This is a pure 3D display -- unfortunately done at a resolution of just 8 x 8 x 8. It's a hand-built LED cube created by Nick Schulze, powered by Arduino, and driven largely by Matlab. Yes, Matlab, an application you probably deleted less than three minutes after signing off on your calculus final. We can't help you find that installation disc again, but we can encourage you to enjoy the video of this 3D matrix of blinkenlights after the break, and you can get the full details on how to build your own at the other end of that source link.
