In 1963 Sol LeWitt put down a few sentences about conceptual art, including this one: “Illogical judgements lead to new experiences.” In the same text Le Witt says that artists are more mystics than rationalists. With her fictional institute Research Raft f°r Underground Riffdogy, Agnes Meyer-Brandis is making a contribution to contemporary myth building by searching for underground icebergs and other possible worlds. To this end she has developed an interactive apparatus whose strategic methodology is borrowed from science, but is otherwise a freely interpretative model of present-day urban landscapes. Her concern is an old one: to learn something about the world. The technology is new: an elegant probe that can be lowered from an exploration tent into the earth’s deeper layers and bring to light the unknown. Fictive and real information, in the form of moving images and sounds of subterranean life forms and rocks, are transmitted visually on a monitor and acoustically via headphones.
