Sandy Noble’s Polargraph Drawing Machine

Via triangulationblog.com

“The whole system is fairly technologically agnostic, but the current incarnation uses an Arduino microcontroller and an Adafruit Motorshield, along with a couple of stepper motors. The application that drives it from the computer is written in Processing. It decodes a bitmap and creates a map of the file using a polar coordinates system, recording pixel position, size and brightness. The hardware requests each pixel in turn, and renders it on the page using it’s own shading and movement algorithms.”
