The 1 and 2 boxes turn on ramps and the vertical 1 and 2 dials control y-position of each and the horizontal ones control x-position. The horizontal dial with the truck controls truck speed. The big box at the top with the man changes his position out of 6 possible on the truck and the vertical dial with the person on the left controls his y-position. The box witht the X next to the box with the man toggles the windshield.
I just got 73374... I started it out with the guy in front of the truck with his feet in a ramp and the windshield on... when it started it threw the guy up in the air and he got creamed and stuck in the windsheild. Comedy gold. I wish I could record an avi of this... any suggestions for programs?
