moire2 (6x)

moire2 [-display host:display.screen] [-visual visual] [-window] [-root] [-delay number] [-ncolors number] [-thickness number] [-fps]

Another example of the fun you can have with moire interference patterns; this hack generates fields of concentric circles or ovals, and combines the planes with various operations. The planes are moving independently of one another, causing the interference lines to ``spray.''
