interference - decaying sinusoidal waves  

SYNOPSIS

interference [-display host:display.screen] [-visual visual] [-window] [-root] [-count number] [-gridsize number] [-delay number] [-speed number] [-radius number] [-ncolors number] [-color-shift number] [-hue number] [-no-db]  

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.  

OPTIONS

-count number
Number of Waves. 0 - 20. Default: 3.
-gridsize number
Magnification. 1 - 20. Default: 4.
-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
Number of Colors. Default: 128.
-color-shift number
Color Contrast. 0 - 100. Default: 60.
-hue number
