The ratios used in the eight animated GIFs on my blog post are

3, 3, 2, 2, 2, 2, 2.5, and 2.75 respectively.

Great Stuff!

Can you add a way to halt the drawing so we can see how the wiggles are formed (the "stars" for example.

Did you find the wheel ratios by trial and error?

The animations are animated GIFs (not Flash videos).

Use a GIF animation software to see the static frame images.

Please explain what is going on here

The big circle is fixed?

The mid-size circle ROLLS on it without slipping?

OR

Is attached to it at a fixed point - while the big circle rotates

The small circle rolls on the mid-size circle? At what rate?

OR

The small circle is attached fixedly to the mid-size circle (which spins?)

OR

The small circle spins - at what rate?

The pen is attached to a fixed point

ON the small circle

OR

Within the small circle

Or rotates around the circumpherence of the small circle - at what rate?

Many thanks
