Setting X Y to zeros yields 2D colorwheel. Adjust to nonzeros for 3D twists. Touch screen or spacebar for new pattern.
Thin lines result in overlapping gap patterns called "moire." To get 3D effect, moves center of "circle" with sine and cosine function. Otherwise, this is the same as my earlier color wheel moire project (which also used thin lines to get the desired gaps, rotates line 1 degree, changes color by 200/360, which uses color effect range divided by 360 degrees, then stamps. Some of the line costumes are color spectrum strips.
