Stenograffia – is an annual international festival of street art, which is held in Yekaterinburg. Theme of the festival in 2013 - "The Theory of Forms." Any flat image drawn on a complex 3D object begins to deform. That’s when the recognizable style of the visual material appears. Starting from this, we have developed the system for the identification of the festival. The same kind of effect helps to break the urban space, and any geometry sticker or stencil with this image leads to visual transformation on a surfaces in a city.
