New software (GA 3D) imports .gml files (Graffiti Markup Language) captured using Graffiti Analysis,
creates 3D geometry based on the data and then exports a 3D
representation of the tag as a .stl file (a common file format
compatible with most 3D software packages including Blender,
Maya and 3DS Max). Time is extruded in the Z dimension and pen speed is
represented by the thickness of the model at any given point. Roth then
have this data 3D printed to create a physical sculpture that serves as
a data visualization of the tag. For the Street and Studio
exhibition at the Kunsthalle Wein, Roth collaborated with an anonymous
local Viennese graffiti writer and had the GA sculpture printed in ABS
plastic. Graffiti motion data of his tag was captured in the streets
(for the first time) at various points around Vienna.
It is always interesting to see how the ‘low-brow’ arts appropriate technology such as motion tracking and 3D printing in a very clever low tech kinda way. The Graffiti Analysis Sculpture has a very loose feel that comes across similar to a mash-up between the Sketch Furniture series by Swedish trio Front Design and Johnny Lee’s Wii remote hacks, both from 2007/2008. It would be great if the Z-Axis could be controlled by something other than time to give more control over the 3D model and make it a really intuitive sketch modeling tool. Sure this kind of interface may never be used to 3D model the latest mind blowing rubik’s cube, but playing around with the Graffiti Analysis Capture Application with nothing more than a webcam and a torch is fun and very addictive…

If you are interested in trying it out..
A version of the Graffiti Analysis 2.0 application loaded with data collected in the streets of Vienna during the course of the installation can be downloaded here: Linux | Windows | OSX GA 3D software and source code will be available at graffitianalysis.com shortly, and of course there is already an iPhone slash iPad app called DustTag that you can downlaod from the app store.

Graffiti Markup Language (GML), is a specifically formated XML file
designed to be a common open structure for archiving gestural graffiti
motion data into a text file. Graffiti Analysis 2.0 saves all data in
GML format for use with other digital systems. For information on how
to capture your tag to GML view the HOW TO page.
The GML development team consists of Jamie Wilkinson, Evan Roth, Theodore Watson and Chris Sugrue. For more information on GML please visit 000000book.com, the official open repository for sharing and archiving graffiti motion data.
