When Russian scientist Alexey Pajitnov released Tetris on June 6, 1984, little did he know he would change the world of video games. Today, the puzzle-game stands as one of the most influential and addicting games of all time -- some even consider it a sport -- and to celebrate its 30th anniversary last month, a European man in Luxembourg named Marc Kerger has created a playable Tetris T-shirt.

Kerger used 128 LED tubes, an Arduino Uno controller board, and a bunch of other high-tech gadget wizardry to make the shirt, which is completely playable. Just like the original arcade, the game is controlled via four directional buttons, and it even keeps track of scores.
