Knex Spiral/Circle Maker

This machine is one that makes spirals and circles on paper. I mostly use this machine for fun, but the designs from it could be useful if you do some thinking. If you want it to go a little faster, you could put a grey motor in it, or gear the green motor down. I didn't, cause this way is way more simple, and the speed is fast enough for me.
