I love the childishness of the Boabab Desk from Phillippe Starck at Hive. It looks like it could be made out of playdough, but could be amazingly functional. It easily hides all the annoying cables from computers. The shelves also look moveable enough to store a CPU without crowding your legs.
The lime green could be pretty hard to fit into most homes, but the other colors are equally unique and a bit more manageable. The red would look rich on oak floors in a bright room, while the aqua would be amazing against an all black wall in a modern, clean apartment.
