The Reality Grinder mosaic problematizes the perception of reality in the time of capital prevalence and the unlimited access to information. The installation exceeds the borders and understanding of a mosaic and places it in a new context. It no longer concerns only particles and relations among them, but also sounds that can generate a clear or a complex and confusing sound image. The interactive installation hence destroys the basic assumptions of a creative medium, especially its stationariness – the observer can move the particles in the finished artwork – and its placement into the sphere of visual art, as the viewer – by moving the particles – designs a new visual as well as a new sound image, in the field of mosaic a breaking and pioneering act.
