Troika is a contemporary artist group founded in 2003 by Eva Rucki and Conny Freyer (both b. 1976, Germany) and Sebastien Noel (b. 1977, France). In their practice, the trio investigates the influence of new technologies on our relationship with the environment. Working across media – including sculpture, film, installation, and painting – Troika explores the shifting boundaries between nature and artificiality, the living and the non-living, ourselves and others. Troika is based in London.

Ultrared, Evergreen, Ocean Blue (2024) by Troika is part of the festival's exhibition Model Collapse at Kunsthalle Wien Karlsplatz.

Suffusing the space with coloured light, Troika’s installation casts the assembled works in the hues of the RGB filter, an optical regime associated with machine vision. These lighting conditions reflect how technical systems shape and alter our perception of the world. The installation varies the light depending on the time of day, subtly connecting the mediated experience of the natural world with the inner realm of the machines that capture it.
