Futuristic Renderings from eVolo's Skyscraper Contest

Every year, the architecture magazine eVolo asks designers to submit avant-garde, futuristic takes on the traditional skyscraper. They recently announced the winners of the annual contest, and the results, as usual, are out of this world. A set of truly surreal renderings, eVolo's picks include a building that takes the "sky" in "skyscraper" quite literally and actually reaches the clouds, a 3D printed world where the Hollywood sign is pastel pink, and several environmentally conscious designs with big goals. Could this be the future?
