[Jorj Bauer]’s Tetris Display is one such project. The project started because [Jorj] had an 8 x 32 WS2812 LED array laying about, and it was high time it got turned into something cool.

He ended up designing an 8 by 16 grid of LED’s that was turned into a game of Tetris. He arranged all 128 LED’s into the grid on a piece of perfboard.

Three MIT students have joined forces to create a massive 6ft tall Tetris game which uses an LED matrix controlled using a pair of Dance Dance Revolution (DDR) controller mats.
