Algodoo

A slightly exotic style of vehicle. They`re a pain to make, but have a few distinct advantages over traditional tracked vehicles. One is that there is no need for a solid connection between the "tracks" and the body of the vehicle, and another is demonstrated in this mini-course.

Arrow keys to drive both the crawler and the example "traditional" tracked vehicle. They don`t collide with each other and cross the mini course at about the same speed.

Also included is a Koch Snowflake fractal that I didn`t make in the bed of the crawler.
