Description:  PolygonFlux lets you experience the flow of energy inside a polygon. In simplest terms, it traces the path of a point bouncing around inside a polygon of your choice, generating a pretty pattern. You control the location of the "shooter" and its direction. The path the point travels is displayed instantly. The path is determined by the Law of Reflection — "The angle of reflection is equal to the angle of incidence" meaning that the point bounces off a side at the same angle it came in on, just like a billiard ball deflects off a bumper on a pool table, or a light ray reflects off a mirror. You can choose a triangle, square, pentagon, hexagon, ... polygons with up to 14 sides! You can choose from a dozen themes for the lines that trace the path of the point. You can add your "Fluxagons" to a scrollable album for later reference and experimentation.
