One of the coolest things about Windows 8 are the Live Tiles, which are like the beautiful love children of widgets and icons. Microsoft thinks so too so they created a hilarious prank that involved a light up floor tile (think Michael Jackson's Billie Jean) and a collapsing wall.

Directed by McCann Oslo, the live tile lays in the middle of the road and lights up when a person steps on it. And when they fully "click" it, the wall falls down and reveals a live concert. It's pretty fun even if it's all probably setup. [PSFK]
