Tetris, a game we all spent many a year playing in the back of classrooms, on the top of toilets and so forth, has never been played like this. Artist Chris Carlson created a 3D chalk art version of Tetris and played a quick round of the puzzle game. It's incredible how detailed it is, you feel as if you could just step right in and play the game.
Except if you were to play the game you'd have to draw out each Tetris piece; note the shadows; erase the Tetris piece; re-draw the Tetris piece and keep on going. It'll take a lot longer but you'll probably have a better chance of actually winning. [Awe Me Channel]
