Light show

Light sources float around stationary spheres.

This function generates an animation of light sources floating around stationary spheres. The moving light sources can also be rendered with smaller spheres (collocated with the light). This is an exercise in simple handle graphics control of surfaces and light sources. Function inputs allow control of size, colors, and number of both moving lights and stationary spheres. Please see the accompanying ?sample_light_show.m? for an example.
