The photo and video above are from the first round of testing for Graffiti Analysis and the Media Facades Festival, which took place on the NightScreen in Berlin a couple of days ago. Thanks to everyone who submitted tags and GML data.

For those who haven’t, there is still time. I have information on how to capture and submit tags listed here, but I’ve also come up with a new way of capturing graffiti motion data that requires only a webcam, a computer and a light source attached to a writing implement. This version (outlined in the diagram below) uses the same Graffiti Analysis 2.0 Capture Application and a similar technique as was previously outlined, but does so in a way that does not require additional equipment or the building of a capture case. Video footage of this technique being used in the city can be viewed here.

All of the submissions highlighted in the video can be viewed and downloaded at the following: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, and 12.

F.A.T. friend and GML collaborator Golan Levin has released the latest addition to the world of Graffiti Markup Language……. GML Stenciler: Laser Cut Patterns from Graffiti Markup Language. He writes:

“We announce the release of GMLStenciler, an open-source software project for converting Graffiti Markup Language (GML) drawings into vector-art stencils suitable for laser cutting. This free tool solves the problem of transforming GML’s widthless linear strokes into adjustably-thickened stencil patterns with automatically bridged islands. GMLStenciler is built in openFrameworks, an open-source C++ toolkit 
for creative coding; it can be downloaded here (with complete source code) for Windows and Mac OSX.”

For more information, downloads and source code, view Golan’s project post.

F.A.T. members, collaborators and friends will be all up in wine country this week. Street artist Mark Jenkins is guest curating an interactive design festival, Les Grandes Traversees, taking place this week and next in three cities on the west coast of France. The festival highlights work from designers, street artists and new media artists that directly interacts with the city. Chris Sugrue and I will be premiering the new Graffiti Analysis 3.0 (coming soon to a browser near you) and collaborating with DJ Rupture on GA3.0’s new audio input functionality. I will also be showing a new 3D printed sculpture of a tag by L’Atlas and Chris will be showing Delicate Boundaries. Theo Watson will be showing a new project, as well as working with Chris and me on merging Laser Tag into Graffiti Analysis, creating the ultimate software for graffiti writers (more on that soon). Theo, Chris and I will also demo the EyeWriter. Other friends of F.A.T. in attendance include Mark Jenkins (who will be showing new work), Improv Everywhere, Paul Notzold (who will be premiering a new project) and Benjamin Gaulon (who will be blasting TEMPT1 tags in paint balls). See below for a complete list of artists.

If you are in France this week come join us….we’ll be in Royan (July 2-4), Soulac (July 6-7) and Bordeaux (July 8-10).

Graffiti Analysis: Sculptures is a series of new physical sculptures that I am making from motion tracked graffiti data. 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. I 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, I 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.

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 was made in Open Frameworks and developed by Chris Sugrue. The Graffiti Analysis sculpture in the Kunsthalle exhibit was printed by RedEye. The project was supported in part by the Kunsthalle Wein. Big thanks to Sydney Ogidan, Catherine Hug, Sigrid Mittersteiner and everyone at the Kunsthalle for their help. Audio in the video above is by Dimlite and was ripped from Theo’s Spring Mix 2010.

GA 3D software and source code will be available at shortly, follow @graffanalysis for updates.

I will also be premiering the new 3.0 version of Graffiti Analysis this week at Les grandes Traversées festival in Bordeaux (more info on that soon).
