While walking around Denver, this guy noticed a building that had several broken windows.  As he continued to stare at this building he noticed that the broken windows were in the shapes of tetrominoes. 

I don't like vandals as much as the next guy, but at least it's Tetris creative.

Update:  Turns out the Tetris Vandalism photo is a fake.  Over at Kotaku, they have posted real photos of the vandalized building.  [via digg]
