Sand Mandala Plotter

This is a mashup of a plotter and 3dprinter ideas and the making af Sand Mandalas. It was exhibited at the Rome Makerfaire.

All my own code, btw. The electronics is a MakerFaireSpecialArduino (An UNO with special logo) and Pololu drivers for the steppers. The laptop is spooling ASCII position commands (sort of simplified Gcode) from a file using Processing, the Arduino is converting XY to "3 wires" and doing the lines.

I have PLENTY of improvments due. All in good time. So many other projects...
