This post used to be on Posterous. I rescued my posts before Posterous shut down and am now sharing them here.
When I first heard of Graffiti Markup Language (GML) I was like “An XML format for graffiti? Pfft!” Then yesterday I was like “Wait, I have a pen plotter.”
gml2unicorn is a Python script that will take GML files and convert them into G-Code compatible with the MakerBot Unicorn pen plotter.
