P.A.R. is a machine that draws your pixel art in the real world, one flipped squisk (square disc) at a time. It has a 37x18 pixel grid made up of these squisks, which are fully 3D-printed. In fact, much of the robot is 3D-printed. It was all designed in onshape. Also, the pixel art pieces it draws are all submissions from its website: https://par.zimmzimm.com.
All of the CAD models and code are open source.
