As a kid, I can remember playing Tetris so long that when I looked at buildings or everyday geometrical shapes, I could see how they would all fit together on a Tetris board. Well, some college students in China have actually made it happen on this scale.

A couple of months ago, I posted a piece about using light as an urban artform. I don't know if this qualifies as art but the execution is amazing. They've taken Tetris to a whole new level (pun intended).
