Harmonographs and Pintographs

Machines that draw are awesome!

Two main categories of drawing machines with interesting mathematical properties that I don’t fully understand (something about Lissajous curves) are Harmonographs (powered by pendulum motion) and Pintographs (usually powered by motors).

There are also a ton of other really cool variations on these machines that involve moving the paper, double pendulums or coupled pendulums, and multiple sources of rotation for each arm.
