Laser Spirograph

A sure sign of a 1970s childhood is a fond memory of doodling with the Kenner Spirograph toy. In the back of my mind I’ve been thinking it would be fun to build something like it into a history appliance. You can already versions online, but I wanted something that could be used at the periphery, rather than the focus, of attention. On a recent trip to Active Surplus in Toronto I realized I could build a version quite cheaply. So here it is: a little too thrown together even to call a hack, this is really a kludge.
