The Sphero Rig allows you to turn your Sphero or BB8 into a drawbot. Print the Sphero Rig Wheels, assemble with a bamboo skewer for the axle, secure a marking pen with rubber bands, and now the Sphero will give Jackson Pollock a run for his money. Here's a video of the Sphero Rig in action: https://www.youtube.com/watch?v=DkbTLNUTNSM
