Graffitis continually create disagreements amongst city officials, building owners, and graffiti creators.  On the one hand, graffiti creators want to display and appreciate their artworks on building walls, but most time the walls are not belong to them. On the other hand, graffitis contribute nothing to the walls’ owners but useless marks.

 

Extrude is an app based on the augmented reality technology developed existed graffitis to animated three-dimensional sculptures. Extrude benefits the walls’ owners by connecting their companies’ website with the AR animated sculptures. When users scan a graffiti and play with the pop up AR sculpture, the company’s website of the walls’ owner will be triggered.
