Are you sick of Tetris-themed decor being absurdly expensive? If one is in that particularly weird little club (hi!), these vinyl stickers, crafted by "Fame" of Vancouver, look like they might be a pleasantly cheap.

Update: A group of fun-loving hackers have built a two-player Tetris rig, called 'Tressling,' controlled by arm wrestling.
