Rings of color generated by a computer simulate interference fringes observed in an experiment with light.
This is what would be seen by looking at a bright surface such as the sky (but not the sun) through a "black light sandwich": two polarizing filters set at a right angle to one another and separated by a sheet of overhead transparency film. Crossed polarizers normally transmit no light. Various wavelengths of light add or subtract to form interference fringes.
