We never really did finish writing up this project before we headed off on our next ridiculous Maker Faire build. And then the one after that was a revamp of this one, renamed ‘Pirograph,’ which – you guessed it – we never really finished writing up either.
One of these years I’ll find time to make a really good version of this project, and will probably write it up as a tutorial for MagPi magazine or something. But I wouldn’t hold your breath. If you’re a final-year student at Northumbria who’d like to explore a project at the intersection of OpenGL, coding instruction/education and computer art… please drop me an email!
