The DuoGraph is the latest drawing machine from inventor and designer Joe Freedman whose Cycloid Drawing Machine took the internet by storm a few months ago. His elaborate devices are capable of producing amazing geometric patterns akin to a Spirograph on steroids. This new creation is quite a bit simpler to setup and use, relying on 7 gears and a number of parameters that can be changed quickly to produce infinite designs. While the DuoGraph is a bit more limited in its level of customization, it’s capable of producing elaborate Lissajous patterns which the larger device cannot. Learn more about it on Kickstarter.
