I was playing with some scripts to create random scene geometry, and I decided to write some scripts to add random lights to the scene, too. These are the results of placing random spheres in the middle of a shell of random lights. The coloring of the lights is (surprise, surprise) random, but specified within a certain color, saturation, and intensity band.
I like working with randomness because I can have complexity without having to add it all by hand. I like that this ends up approximating the smoothness of a global illumination setup.
