Cool. Input to developer: offer gear numbers that are co-prime (or absolute primes) to each other. Results in maximum number of circles until you return to the original point.
Thanks! I chose the same set of gears that shipped with the original Spirograph. Also note that you can achieve a similar effect by pressing "," or ".", which offsets the gear by one tooth, and then re-drawing the complete design.
