Constructed just for fun. The pintograph uses two arms, rotating slightly out of phase, to move a stylus and trace out a complex geometric design. The stylus in this case was an LED light, and the image was captured with a 35mm camera on the bulb setting. 

 The completed pintograph. On the circuit board is the power supply and DC motor controller.
