Graffiti Analysis: Barcelona

Graffiti Analysis Sculpture
Barcelona, 2010
ABS Thermoplastic
31 x 20 x 35 cm
This Barcelona specific installation of Graffiti Analysis is currently on exhibition as part of Kitsch Digital. The sculpture was created by algorithmically averaging the motion captured data from local graffiti writers and produced on a rapid prototyping 3D printer.
(.gml data from the Barcelona Graffiti Analysis sessions can be downloaded here.)

Zine and Billboard release….

Last Wednesday marked the release of a zine I created for Beton Blumen and the opening of a related billboard at the Street Art Passage in Vienna. More images here.

Graffiti Analysis: Tudela…. Seeking Tags

I will be in Tudela, Spain all of this week taking part in the 42º Latitud Arte-Tudela Festival and projecting .gml tags with Graffiti Analysis. If you are a graffiti writer interested in having your tags projected around town please get involved by either:
1) Sending me an email (info[at]graffitianalysis[dot]com) and we can set up a time to meet to digitize your tag.
2) Stopping by the Castle Ruiz Tuesday or Wednesday between 3:00pm – 4:30pm and looking for a redhead sitting in front of a yellow laptop.
3) Uploading your tag in .gml format to I will be going through all of the most recently upload tags each day and picking out ones with nice style and flow to project around town each night. For information on how to capture your tag into .gml please go here.

Graffiti Analaysis: POV Can

(View in fullscreen for best results.)
Graffiti Analysis: POV Can is a low tech DIY spray can modification in which the LED light source doubles as video illumination and motion tracking input. The GML (.gml) data of the graffiti tags featured in the video can be downloaded here, and the Graffiti Analysis software and source code can be downloaded here. GA:POV Can was created in Vienna last week as part of the BLK River Festival.

Graffiti Analysis 3.0 Is Here

Graffiti Analysis 3.0“It’s hard to believe we could fit so many great ideas into something so thin.”
Break out your digital projectors, markers, turntables, lasers and 3D glasses, because Graffiti Analysis version 3.0 is finally here. For information and downloads go to (source code available on github). Your one stop shop for ink and pixels.
New features include:
– audio input
– architectural awareness
– laser input
– keyword based .gml RSS playback
– red / cyan 3D effect
Graffiti Analysis is an extensive ongoing study in the motion of graffiti. Custom software designed for graffiti writers creates visualizations of the often unseen gestures involved in the creation of a tag. Motion data is recorded, analyzed and archived as a Graffiti Markup Language (.gml) file, a specifically formatted XML file designed to be a common open structure for archiving gestural graffiti motion data.
Graffiti Analysis is a project by Evan Roth. Software development by Mzz Chris Sugrue. Support for GAv3.0 from Les Grandes Traversees. Graffiti Analysis was built in Open Framewerkz, with additional code contributions from Theo Watson (laser input integration), Kyle McDonald (audio analysis) and ps / TPOLM (.gml RSS system).
GML Week II continues…

Graffiti Analysis and the Media Facades Festival Continues…

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.

FATies in FFFFFrance…

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).

Here is a sneak peak at the new Graffiti Analysis 3.0 from a test last night in Royan:

Mark Jenkins, Sandra Fernandez, Chris Sugrue, Aakash Nihalani, Paul Notzold, Theo Watson, Evan Roth, Charlie Todd (Improv Everywhere), Jared Gradinger, Masagon, Sydney Ogidan, Truthtag, DJ Rupture, Erell, Ruskig, Benjamin Gaulon

Graffiti Analysis: Sculptures

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).
