Graham Hill, founder of the blog Treehugger, took the stage to announce a competition to re-design a 420-foot-square apartment in the most fantastic, innovative, and green way possible. Ideally the space, with parsed-down stuff, the help of technology, and some creative corner-cutting could be host to a work-at-home city-dweller with room enough for two guests to sleep over and sit-down dinner parties for a dozen. Dubbed LifeEdited, the prize pot contains $70,000.
