Clever, beautiful and fun: PrimoGraf Drawing Machine (Mechanical mathematical drawings)
This thing is wonderful. It’s not cheap but then a lot of work has gone into making it.
It comes with seven prime number based gears and two sets of rods. They claim an infinite number of drawings can be made with it. I think that is probably not true, but I’d be happy to be proved wrong.
Whatever the actual capabilities the results are lovely and the process is fascinating. There’s a video of the machine in action on the site page so click through for a kinetic view.
