I’m excited to announce the official launch of a new project I’ve been working on with Mozilla. Mark Up is an online statement of solidarity in support of a web that should remain open, free and healthy. It’s similar in concept to an online petition where everyone is invited to add their signature, name or mark. Each mark is rendered in 3D using HTML5 and connected end-to-end to form a continuous line, representing a unified global statement on the fundamental importance of an open and free internet. Add your mark and become part of the line that connects you, me, Lawrence Lessig, James Boyle and many others:
http://markup.mozilla.org

Mark Up is an open initiative with both the data and source code freely available. All of the marks are saved as .gml (Graffiti Markup Language) and can be used interchangeably with many other applications.
For any data nerds, the entire collection of marks will be made available here and updated periodically as the site grows.
Much of the credit for this project goes to Laura Mesa and many very busy Mozillians. Development for the project was done primarily by The Barbarian Group.

Vote for Graffiti Analysis & GML in the Transmediale & Mozilla Open Web Award!!!
Here’s how:
1. Create a Mozilla Drumbeat account: https://www.drumbeat.org/user/register
2. Check your mail to get your password and validate your account.
3. Go to the GA/GML Project page on Drumbeat and click “vote” in the upper right corner: http://www.drumbeat.org/project/graffiti-markup-language
4. Leave a comment related to “what you – in particular – like? How do you think the project supports the open web? Would you want to somehow contribute or get involved? Your vote and input directly influences the final decision.”
As you can see, GA/GML is currently waaaaaaaay behind in the race, so it can use all the help it can get. Once you have voted please accept my thanks and this sticker.

I’m headed to Barcelona on Wednesday for the Mozilla Drumbeat Festival. I’m going to be running some formal (and some informal) sessions surrounding Graffiti Markup Language. Hackers can find me on Thursday (Nov. 4th) at 11:30am in Monochrom’s hackerspace bus, which should be parked in the MACBA courtyard. I will also be running an informal / un-official session for local graffiti writers interested in either: 1) having their tags motion captured into .gml (like this), or 2) experimenting with mini bombing sessions using Spray Can POV cams. Send me an email if you’re interested and I can give you the details – info[at]evan-roth[dot]com
***Update***
I’m also giving a talk on Friday November 5, at 19:30 (free entrance) at:

GML Field Recorder Challenge (€1,200)
A design challenge to create an easily reproducible DIY device that can unobtrusively record graffiti motion data during a graffiti writer’s normal practice in the city.
The GML Field Recorder Challenge is a DIY hardware and software solution for unobtrusively recording graffiti motion data during a graffiti writer’s normal practice in the city. The winning project will be an easy to follow instruction set that can be reproduced by graffiti writers and amateur technologists. The goal is to create a device that will document a night of graffiti bombing into an easily retrievable series of Graffiti Markup Language (.gml) files while not interfering with the normal process of writing graffiti. The solution should be easy to produce, lightweight, open source, cheap, secure, and require little to no setup and calibration. The first person or team to create the device and publish corresponding source code and HOW TO guides (as outlined in the rules) will receive €1,200. For a complete list of design requirements go to graffitimarkuplanguage.com/challenges/gml-field-recorder-challenge.
The GML Field Recorder Challenge (including the prize money) is funded entirely by Constant, which is a non-profit interdisciplinary arts-lab that is based and active in Brussels since 1997.

GML Week SE02 EP03 is happy to announce the public launch of the official GML community home on the Internet: graffitimarkuplanguage.com. This site will act as an archive for GML related projects, source code, updates and community discussion. graffitimarkuplanguage.com will also be home to the official (and newly updated) GML v1.0 spec document. Hackers and graffiti writers please come over and play.
graffitimarkuplanguage.com

The GML v1.0 Spec Doc was created by: Golan Levin, Evan Roth, Jérôme Saint-Clair, Chris Sugrue, Jamie Wilkinson and Theo Watson.
Huge thanks to Constant for their support of the GML community website and inaugural GML Challenge.
graffitimarkuplanguage.com was built in WordPress using wpfolio (THE WordPress theme for artists).

I am excited to introduce a new way to submit tags to Graffiti Analysis for the Media Facades Festival 2010. Laurent Van Basselaere (Coding with Attitude) created a web-based GML canvas recorder that sends data directly to #000000book, where it is stored in Graffiti Markup Language (.gml) format. To get started click here and follow the directions at the bottom of the page (more methods for recording graffiti motion data are described here). The deadline for submitting tags has now been extended to September 15th. Get your tag up big, bright and all over Europe… without leaving your cubical.


The next round of testing for the Media Facades Festival is complete. All of the tags selected in the video clip above were displayed on loop above the skyline of Belrin on the NightScreen. You can download the .gml files (Graffiti Markup Language) of these tags here: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10

Victor Martins has been doing some Viscosity experiments in Processing:


And Mike Creighton has been using .gml with Flow libraries:

Chris and I are currently working on a 3D Graffiti Analysis / GML application for exporting .stl files. Downloads and source coming at the end of June.

Achim Kern (from derivative.ca) has developed a GML reader for TouchDesigner. Source code available here.

The 000000bot team demoed this iPad to Graffiti Analysis to 000000book to iPhone to robot to pen to paper system at Stanford’s Robotics Week.

Keegan3D is working on a GML importer for Maya. More on this as it develops.

YouTube user 000000bot posted this footage of a robot drawing from the Graffiti Analysis iPhone App. Long Live G.M.L.!

App, source code and tutorials coming this summer. Props to Mike Frumin’s open source OGLE project.
