Press Forward: Trackmania

I've been completely engrossed in these Press Forward track builds for the video game Trackmania.

If you've never seen them or heard of them, the idea is simple: The player essentially just presses forward (accelerate) the entire time and lets the track do the steering of the car for you. What results on these custom tracks is a winding, twisting, jumble of a mess that is just so fun to watch.
