The kinetic audio-visual installation Offset by Andreas Lutz analyzes the manipulation of the medium itself and the discrepancy between physical reality and visual perception. Geometrically precise patterns are projected on an as even perceived object. Through a physical deformation of the object, these patterns additively change and transform into different states. Through the continuous manipulation of the medium itself, there is a discrepancy of what is actually there and what is only perceived visually. A stretchable fabric is moved by motors at different points along the Z-axis. The motors are synchronized to the sequence of the audio-visual dramaturgy. Viewed from the front, the real displacements are objectively perceived as distortions on a two-dimensional surface. When approaching the installation, the whole object will be understood as three-dimensional and the physically induced distortions get visible by the varying depths of the surface.
