Done in about an evening as a first project using the system, I'm actually quite surprised it turned out decent looking for a first go from scratch thing, for both visual stuff and physics.
Pretty basic functionality, Left, right and up arrow keys nudge the ball, z toggles the trail on and off.
Feel free to pick it apart for your own usage.
