Epiphytes are organisms that grow on the surface of a plant and derive moisture and nutrients from the air, rain, water or from debris accumulating around it. They have no attachment to the ground or other obvious nutrient source and are not parasitic on the supporting plants.

Referring to these organic entities the site specific audiovisual work Epiphytes [M496+Q8] is generated by the climatic conditions around the trees of a forest near Drebkau, Germany.
Six custom made modules are attached to the trees and directed to a central suspended sculpture. Each module is composed of one Raspberry Pi, an Arduino board, sensors measuring humidity, temperature and light amount, a laser pointer and a speaker.

The system behaves like a small network, in which each element plays its role in the generation of the sound and light composition. Here the main inspiration was the invisible carbon exchange trees have through their root network, that link them together with the help of fungi (mycorrhizal network). The sounds produced by each module generate an abstract dialogue between trees covering a path at the forest entrance. Like a living organism, the behaviour of the audiovisual work changes over the time of the day and the passing of seasons, influenced by weather conditions and humidity of the air.

The transparent polycarbonate structure is refracting the light from the sun during the day, while in the night, the laser beams coming from the modules create volumetric views of the light sequences of the installation.
