Seems to be somewhat out of date, possibly even discontinued, but the site is still up, and it's interesting. From their website, "LUX LOGIS was founded in spring 1991 as an union of about 20 artists in Berlin in order to progagate a nonchalant cultural use of technology and new media. The individual artists are influenced by different areas like fine arts, film, video art, design, philosophie, communication science, information science, computer science, physics and robotics. Lux Logis, as a node for electronic arts in Berlin, is interested in cooperation and exchange with institutions, autonomous groups and artists in the world and realizes interactive PROJECTS within the Internet."
