From Urban Prankster, check out this video of a dorm “prank” by somebody in Poland.  Something this coordinated is obviously not just a prank.  If it was really just regular people flipping some light switches, then it is one of the awesomest things I have ever seen.  However, it seems a little too complicated and a little too perfect…if it is just something computer controlled then it is kind of lame.

There are a few more videos off of that Urban Prankster link, so if you liked that one, check them out.
