I built a drawing machine based off of Makelangelo software. I think that I had a pretty nice solution to the problem and was able to make a very nice looking and working machine. I documented the entire process here. This includes step by step instructions to make your own machine, downloadable files to create all the pieces, and links to both the software and resources that I used.setup

And a couple of the drawings that I made.
