Through the design of wall coverings, I aim to challenge conventional perceptions of a wall surface. By employing innovative use of materials and techniques, it is possible to create optical effects that are activated by the viewer's movement. This method has allowed me to turn a "regular" interior wall surface into a field that is able to give feedback about a viewer's movement. By putting the viewer in the position to have a sensory dialogue with the surface, via wall covering, I can create an experience that is personal, unexpected and delightful.
