DuoGraph, A New Compact Drawing Machine by Joe Freedman


DuoGraph is the latest drawing machine created by inventor and designer Joe Freedman, whose Cycloid Drawing Machine took the internet by storm a few months back. His uniquely elaborate devices are capable of producing beautiful geometric patterns akin to a Spirograph on steroids.

His 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 a larger device cannot.
