The Computer of Tomorrow - B-membrane
Conceived by Korean designer Won-Seok-Lee, the "B-membrane" is one of the most interesting PC prototypes I've ever seen.
The B-membrane looks nothing like a conventional computer, more like a spaceship or space station, but it is indeed a PC, able to project an image of your desktop on any surface you can point its omni-directional projector at, thus rendering even the slimmest LCD monitor useless. It also has a membrane keyboard and mouse that appear only when you need them too, and an optical drive.
The B-membrane isn't useless even when it is shut-down; its smart projector turns it into an ambient light-effects system to spice up the look of your crib.
