There’s a graffiti supplies shop in town, Spectrum Arts, run by this dude called Mark. I approached him about putting a machine in his window – he’s got some covetable glass, and is a nice guy.
It’s been there for a while, but I’ve just got the kit to fit a big fat chalk pen in it. I used this gondola that Stuart Childs designed which did the trick nicely. Thanks to Stuart for this – very timely, and I think I got some great first results out of it too. The slow speed of the vector drawing means that gravity can keep the tip supplied with ink.
Am hoping to formulate a sequence of drawings to go in the window, but would love to see something graffiti based, am thinking of a GML-aware system that can accept tags from all over the internet and mark them out on the glass. For now, it’s just manually controlled, but it communicates using an XBee and has an SD card too, so that’s nice.
