It is! Excellent job!
In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.

Re: [Fractal Spirograph] Fractal Roulette
What are the ratios between the circles? I see the five pointed star.

Hi anonimnystefy,
Thanks for the link.
Hi bobbym,
You're welcome.
Hi John,
What are the ratios between the circles?
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.

Re: [Fractal Spirograph] Fractal Roulette
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.

Yes.

Hi benice;
The one that consists of blue hexagons is a nice one!

Re: [Fractal Spirograph] Fractal Roulette
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
