You can set color slider ~ even change it as it's drawing. Takes a while to draw. So sit back and watch some TV while you let this run in the background.
Was thinking about how there are approx 6.28 radians when you swing a full 360-degrees. Wondered what would happen if you kept turning around the circle in radian-steps, then drew a line in. As it turns out, it pretty evenly covers the area, and reminded me of an iris.
