A gift for my wife. The toy, not the picture. She had one when she was a
kid and still talks about it.

Can make the traditional Spirograph curves, in addition to some more
exotic stuff I made up. I always thought the best shapes were the ones
formed by "simple curve, move a few teeth clockwise, simple curve, etc."
These, are, however, just one closed curve each to show the toy.
The computer version has the advantage of thick lines, outlined lines,
bigger loops, etc. These are selected from a larger group of randomly
generated curves.
If she makes anything with it, I might post it here.

Nice - I used to have a plastic drawing set with all kinds of little wheels
with gears around the outer edges and holes in the middle. You could jam
pens in there and the rotate the wheel arouned the circumference of the a
big ring pinned to a piece of cardboard with a paper beneath it. Using
different holes in the inner piece of round plastic would give you
different shapes - this looks exactly like what you put up.
Doing this with Pov is a novel idea...!

That's exactly the Spirograph I'm talking about. My wife wanted to buy
one, but I made this for her instead. Easy to use, as things like the
line thickness are generated algorithmically based on the complexity of
the curve.

High!
Really impressive! Could be very useful when reproducing Islamic art
with PoV-Ray... so be prepared to find some of your spirograph patterns
one day (let's say around 2020) in some mosque in Virtual Herat or
CyberMazar...
See you in Khyberspace!
