Description: 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, 000000book.com, 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 or Linux desktop systems.
