Beams of light become artificial sonic creatures capable of procreating and evolving in Matthias Lohscheidt's installation Evolution Of Silence. The interactive sound piece consists of a virtual environment that's controlled by evolutionary algorithms and can also be affected by people coming into contact with the beams.Loshscheidt explains: "Each creature sounds in a tone, that is defined in its DNA, and is visually represented by a ray of light inside a holographic projection. The population of these creatures is steadily evolving in an evolutionary algorithm."

The virtual environment that the forms live in has a certain key as its base state, the creatures' tones waver around this and the more they fit it the louder they become. In turn this makes their beam of light stronger and wider, making them more attractive to other light beams so they live longer and can "mate".Beams that do not correlate to the environmental key are weaker and die out, so the world "evolves from a disharmonious and chaotic soundscape to a harmonic structure, fitting more and more the key provided by the environment."
This key changes every few minutes so the state of this virtual world is thrown back into chaos, but will evolve into harmony again over time. If visitors wave their hand over the beams this can also affect the environment by causing the weaker "deviant" beams to energise and become strong—these disharmonies slow down the tendency of the world towards order, so it fluctuates between chaos and harmony becoming a kind of ethereal instrument that can be played.Images courtesy of Matthias Lohscheidt@stewart23rd
