The 3 wheel Spirograph requires 9 inputs : the radii of the 3
wheels, their speeds and phases. Key in these in the respective
cells to generate the spirographs. Setting one of the radii or one
of the speeds to 0 creates a 2 wheel spirpograph. Note that the
numbers can be positive or negative.
For example, see the screenshot below which shows a 3 wheel
spirograph created by setting all the radii to 1, the speeds to -5,
7 and 1 and all the phases to 0.
The spirograph shown below was made setting the radii to 17,2 and 2
and the speeds to 1,17 and 100. All phases were set to 0.
See this article by Victor Lua~na Cabal for a good description of spirographs and for more samples of 2 and 3 wheel spirographs.
