There are more than a few approaches to the twinned problems of insufficient plug space and cable tangle, but the obscenely overdone Outlet Wall concept, courtesy of Ironic Sans, is easily my favorite.
Say what you will about feasibility—the Outlet Wall looks fantastic. Replacing the whole surface with hundreds of live outlets is a practical guarantee that you'll burn your entire house down, so in practice, the wall would have to be made mostly out of dead sockets. But discussing the practical implications of the Outlet Wall feels dumb, and kind of misses the point.
Aside from the neat switchboard aesthetic, the Outlet Wall's message is what really resonates: This room here? This room is for technology. [Ironic Sans via Gadget Venue]
