Carsten Höoller, creator of the magnificent slides shown at the Tate Museum earlier this year (above left, click on image for detail) and a beguiling room of 10 ft. mushrooms hanging from the ceiling (above right, click on image for detail), is a renaissance man of sorts. A scientist with a concentration in olfactory communication in insects, he saw a problem with a profession of ever-increasing specialization. In the 1980s Höoller turned to the wide-open field of contemporary art, creating interactive and wondrous works that poke at one's perception of experience. Inducing doubt and confusion, the majority of his installations and sculptures seem to use the audience as subjects of perceptual and psychological experimentation.
