The Lego Halloween Challenge

About a month ago I started to build a robot for a Halloween Contest  on Lego's site for the Mindstorms NXT. Now, two days before Halloween, I hit the "Post" button and, and, I finished!

The robot is a spider who, when a unsuspecting victim steps under it, drops down and scares the victim half to death. Here he is, the moment of truth has arrived, Aarrroooo! (That was the dog.) Enjoy the video!
