Graffiti Analysis iPhone Edition: DustTag
A pocket sized digital graffiti blackbook designed for documenting more than just ink.
DustTag is an iPhone application designed for graffiti writers that visualizes the motion involved in the creation of a tag. Motion data is recorded, analyzed and archived in a free and open database,, where writers can share 3-D animated representations of their hand styles. All tags created in DustTag are saved as Graffiti Markup Language (GML) files, a new digital standard used by other popular graffiti applications such as Laser Tag and EyeWriter. DustTag is fully compatible with the Graffiti Analysis 2.0 software suite, which is available online for free on the DOWNLOADS page and can be used to playback DustTag creations from the iPhone on OSX, Windows and Linux desktop systems.
Graffiti Analysis: DustTag was created by Chris Sugrue and Evan Roth in OpenFramewerkz. For more information and source code go to the DustTag project page.
Download from Apple App store
(Free as in freedom, not as in free iPhone apps.)
Note: The current version of DustTag is available for iPhone OS v3.1.2, but will shortly be updated for compatibility with v3.0 and higher.
