Big Trak I had one in my 20s and my substance abusing buddies had great times programming it. It was fun to set it to roll up to a new girlfriend and shoot her as she started to pick it up. I spooked a few girls with that. I took it to work one time and had it run through the warehouse. too bad it was never upgraded to do more. Today it would fun with 100gig HD and some real lasers.
