Hi Michael,

The first script attached, Epitrochoid, makes epitrochoids. The Spirograph toy does these, as well as hypotrochoids.
Much of the code for the script is in the .htm file, and it works fine. Thought I would try a circular track model for a Roller Pinion System.

The second script attached is EpitrochoidSliderBadFlicker, with the code in the .js file. The "onmousemove" slider is
causing bad flicker. Is there any way to fix this?

The third script attached is EpitrochoidSliderHTMstyleSomeFlicker works pretty well, with some "onmousemove" flicker.
Is there any way to improve this flicker?
