SlowLight

Bob Gallup and I made a piece for the Winter Lights show at Vermillion Gallery in Capitol Hill. Bob posted a video (the action starts at about 1:11)

Two axis stepper motor driven UV LED drawing patterns on a plastic screen with phosphorescent paint. The controller is you average ordinary Arduino with an Adafruit motor controller board. Bob wrote some really cool turtle graphics inspired code to draw geometric patterns.
