Graffiti Analysis: Sculptures is a series of new physical sculptures from motion tracked graffiti data. Time is extruded in the Z dimension and pen speed is represented by the thickness of the model at any given point. This data is then 3D printed to create a physical sculpture that serves as a data visualization of the tag.
