Please! The 150/105 and 144/96 were my favorites, but I usually used the outside. The outside rings could be added as two new fixed options. Great wonderful app, thanks!

I'm only just aware of the existence of this great app, and this was one of the first options I was looking for: how do you get the moving part outside the ring? Then I came across this message. So I can't... :-( ...yet.

Thanks for reviving youth memories from the 70s! Loved my spirograph. :-)
