Mechanical Laser Show

Evan built this nifty mechanical laser show on his 3D printer. The gizmo has two rotating cams that tilt a laser pointer up and down and from side to side in such a way that it draws different 3D shapes. In this video he explains the math behind it. You can download the model at Thingiverse
