Analysing the light and the context of Haus am Horn came the idea of the interactive colour projection installation, as part of an exhibition about colours, to take place in the main room in Haus am Horn. Something that would interfere with the visitor´s perception of the room by creating tangible images and the same time allowing the exhibition to be interactive. Based on the colour theories of the masters of the Staatliches Bauhaus in Weimar and on the innovative creations of the Lásló Moholy-Nagy were he combined art and technology.
