[math-fun] Somsky and Spirograph

I believe we can make a set of Somsky rigid planetary gears that work using an original Spirograph set. This set includes wheels of size 24, 30, 32, 40, and 42, and a ring of size 96. Putting this together you should be able to use a sun of size 24 and four sets of planet gears 30+42 and 32+40. I believe this is the only combination that works with the default set of gears. It's quite possible there isn't enough space to do this without the gears overlapping. But it would be fun to try. Does anyone have an original Spirograph set? -- -- http://cube20.org/ -- [Golly link suppressed; ask me why] --
