Yannick Hofmann (DE), Johannes Jensen (DE) Composing on Wheels

2020 – 2021, interactive installation

A sword of Damocles hangs over the heads of media artists regarding their disproportionately negative ecological footprint. The reflection on energy efficiency and sustainability in media artistic production is inevitable. The interactive installation Composing on Wheels represents an energy-autonomous stand-alone solution for the production of electronic music, powered by the creative energy and muscle power of the visitors in a collaborative effort. Up to two visitors sit and pedal on bicycles to power up the installation: to this purpose, two modified bicycles are connected to belt-driven generators, which power a sensor-controlled device consisting of an energy-efficient single-board computer and several photo-resistors. Using this device, other visitors can make custom graphic notations sound, for which rhythms and sound progressions of musical phrases are individually designed on paper. The installation makes the necessary energy resources visible and tangible, which are otherwise hardly perceived in the electronic world. However, it also raises more questions than it actually answers.

Yannick Hofmann (b. 1988 in Offenbach a.M.) is an artist and curator working at the ZKM | Center for Art and Media Karlsruhe since 2014. Artistically integrating methods of the maker scene (e.g. creative coding, physical computing, hardware hacking), his concept-driven artworks oscillate between time-based and space-based media exploring real-world phenomena with an ironic yet thought-provoking twist. He has been internationally active in Central, Southern, and Eastern Europe, Russia, North America, Southeast Asia and India.


Johannes Jensen (DE)

Johannes Jensen (b. 1981 in Hamburg) is an artist and electrical engineer whose artistic practice is characterized by the integration of moving machines and electronics into installations that perform nonsensical actions. He has received numerous awards for these works.
