Muharrem Yildirim has developed the first major contender towards solving the GML Field Recorder Challenge, which is a 1200 euro prize to produce an easily reproducible DIY device that can unobtrusively record graffiti motion data during a graffiti writerâ€™s normal practice in the city. The GML Recording Machine uses a hacked mechanical mouse in combination with an Arduino to measure the length of two strings attached to the graffiti writer’s feet. The motion captured data is stored in an on board SD card and, with a simple script, is later converted to Graffiti Markup Language (.gml) format. An instruction guide for how to build the device from low cost materials will be on Muharrem’s blog shortly.
The GML Recording Machine is an exciting step forward in the development of technologies for real (as opposed to simulated) graffiti.
