This demonstrates an interactive lens system. Move any blue dot to control the location, thickness, and curvature of the lenses, or the starting point or angle of the rays. When you see rays shooting off at odd angles, you are seeing an accurate depiction of what happens when rays either miss the lens or are reflected instead of refracted because of the angle of incidence.
