DESCRIPTION
Another color-field hack, this one works by computing decaying sinusoidal
waves, and allowing them to interfere with each other as their origins
move.

-
Number of Waves. 0 - 20. Default: 3.
- -gridsize number
-
Magnification. 1 - 20. Default: 2.
- -delay number
-
Per-frame delay, in microseconds. Default: 30000 (0.03 seconds.).
- -speed number
-
Wave Speed. 1 - 100. Default: 30.
- -radius number
-
Wave Size. 50 - 1500. Default: 800.
- -ncolors number
-

- -color-shift number
-
Color Contrast. 0 - 100. Default: 60.
