Now this is certainly one of the stranger concept PCs I have come across – the E-Ball courtesy of designer Apostol Tnokovski. He not only makes this 6″ round PC one of the smallest in the world (by desktop standards anyways), but it also packs quite a punch where specifications are concerned. Never mind on whether the physics of current times will be able to conjure something magical like this – concepts, after all, are meant to stretch your imagination. Does the green color have anything to do with being environmentally friendly as well? Food for thought. Features include a pop-out laser mouse, a pico projector and a laser keyboard.
