Play tetris on a Tshirt

Here is a project I just finished, just in time for the 30th anniversary of Tetris. a T-Shirt you can play. with an arduino uno, 4 AA batteries and 128 LEDs.
I always wanted a playable Tshirt, well now I made one myself. based on the pumpktris from instructables.
let this run in the background for music :) • Original Tetris theme ...
