Based on the work of Dr. Joel Hass and Dr. Peter Scott Instructions Choose the grid size. The fine grid is 3 pixels wide and is the slowest yet most accurate approximation to a smooth flow. The medium grid is 6 pixels wide. The coarse grid is 9 pixels wide.
Curves collapse quickly, yet still somewhat smooth.
The super coarse grid is 15 pixels wide. Curves collapse very quickly. Color changes will track the progress of the curve. Currently, the color changes every 100 iterations of the disk flow. If you choose to not leave a trace, the old curve will be erased before the new curve is drawn after each iteration of the disk flow.
