Working Gears?

[marmak3261]

Here’s a good topic with a few links to gear generators.

Gearify, has anybody used it?

I was going through some old links and ran across this interesting one, Gearify, and was wondering if anyone has used it before? It might be useful for those who wanted to make their own spirographs as well. [Introducing "Gearify" - non circular gear creation software.
