After that traces of his activities appear online. Most notably, his installation Blue Shift [LOG. 1], introduced last Summer at Isea2006, aims to question the status of the utilitarian in art and science and push interactive installation art into Darwinian realms (detail of the installation on the right). A community of single-cell algae, water fleas, fish and water snails is set up in the exhibition space. Visitors induce a gradual microevolution of the - genetically determined - light-responsive behavior of the water fleas. When the system is in standby, yellow lights illuminate the aquaria from the top. The water fleas are attracted to this light and swim towards it. Whenever a visitor is detected in proximity of the installation, blue spotlights are activated. Water fleas, repelled by this color, flee downwards and pass through holes in a false bottom in the aquaria... where fish are waiting to wipe them out.
