Day 3 of GML Week brings us the first major update to a project that I started working on back in 2004 as part of my graduate thesis research. I have teamed up with artist and OpenFrameworks bada55 Chris Sugrue to create Graffiti Analysis 2.0. The GA2.0 software suite consists of (i) the Capture application (PC/OSX/Linux), which records graffiti tags in motion and exports them as .gml files; (ii) the Playback application (PC/OSX/Linux), which imports .gml files and creates data visualizations based on gestural graffiti movement and (iii) DustTag (the GA2.0 iPhone application), which captures graffiti tags and uploads them directly to, an open online database of .gml data. GA2.0 is an ongoing initiative that has been used to capture data from prominent graffiti writers including SEEN, TWIST, AMAZE, KETONE, JON ONE and KATSU, all of which can be downloaded for playback at

GA2.0 is available online for free in an effort to build the world’s largest archive of graffiti motion data and encourage collaboration between graffiti writers (by uploading data) and hackers (by building systems which utilize that data).
