Re:Show HN: Sketch, connect and simulate gears and chains by caseorganic on Wednesday July 31, 2013 @12:30PM (#6134950)
Love this! It's very intuitive and fun to draw gears of different sizes and hook them together.

I'd love to be able to make more complex gears. I immediately tried to make a compound gear set with three gears and two different bands.

That got me thinking about "Incredible-Machine" puzzle features and how fun it would be to actually try to build working things like clocks, bikes and machines with this.
