The kinetic installation Hypergradient by German artist Andreas Lutz repeatedly changes between two states: the statement state and the interpretation state. The statement state displays a sequence of characters of a distinct semiotic system, which can be described as a deputy for all known semiotic systems. These single characters are grouped to strings and then form string orders into an abstract proposition. When the installation reaches the interpretation state, the whole space changes into darkness. Through the constant change of light, the physical deformation of the surface and the consequent modification of perception, the original statement now has to be interpreted by the observer.
