The perceptual meanings of now, later or (in) finiteness shift and intensify - on the outside still real and now, inside a confined space, surreal cloud formations in always identical, repetitive and never ending movements. The new cloud images transform the space into a magically sensual projection landscape. They are reminiscent of the master of deception, René Magritte who was deeply involved in the perception of reality in his work, trying to expose the invisible through sight and thinking: to see things differently. In this way, Muller directs the view behind the light-reflecting surfaces and motifs. With the multi-part medial floor installation, the general viewing habits are lifted. There is a change of perspective from above and below, in which not only the room situation is renegotiated. The supposed mirror image in the usual reflective surface disappears behind the clouds. At the same time, the floor opens and connects the here and now with the imagination behind it.
