2 | * A Projection of sin wave in 3d space. | |
3 | * It sort of looks like an animal swiming around in water. | |
4 | * Angle sliders are sort of a work in progress that allow yo to change the crazy ways it moves around. | |
5 | * Hue slider allows you to control how different the colors are along the wave. | |
6 | * | |
7 | * This code copied heavily from Tim and Slee. | |
