If you're sick of bulky PCs, then the Relevo PC from designer David Alabau Raga may be able to cure what ails you. This PC is designed to be projected out of a 15-inch tube.
The Relevo PC is designed to be a "tablecloth PC". The PC will unfurl from the tube, with all the components needed being onscreen. While I am not exactly sure how this would be better than using an actual desktop computer, it sure does look and sound cool. Check out the featured gallery to see more shots and a detailed explanation of the Relevo PC.
