Kohei Odaka's entry into Designtope's "The Restroom of the 21st Century" contest took first prize. Titled "Black Cube", the rectangular room is made from charcoal, which dehumidifies, deodorizes and de-ionizes the air. The dark room has just one source of light: a luminescent toilet seat. via ::Reluct ::Designtope Comp The cube, says its Japanese designer, soothes the body, "and the reduction of visual information to the bare minimum sharpens the senses...This space functions as a place to cleanse not merely the body but also the soul. It is a kind of meditative space, rather like a tea ceremony room; a place to emancipate the very body and soul of modern man, and let us make a fresh start." Hmmm....we're not so sure about that last part Kohei, but we can think of a few public toilets we'd like to see de-ionized.
