Poincare Pool

This is a game trying to help you understand the Poincare Disk. Your goal is to "bounce" a ball off the (geodesic) walls so that your ball will hit the boundary drawn in red, and to use the fewest "bounces" possible. The ball will move along a "geodesic line", which is determined by the "Poincare distance". It is not a straight line, but rather a part of a circle. Try it, you'll quickly get the hang of it.
