French design team Lauren and Paulina Bibi unveiled these Mac and iMac covers at the Parisian Apple Expo. They aren't online yet but you can e-mail the designer sisters and they'll send you one. $40-$50 each.
Implications - These mischievous monster covers have the power to transform your seemingly harmless Mac into a fearsome and hilarious beast, so it's no surprise that Lauren and Paulina Bibi have been literally inundated with demand. The only problem I can foresee with this oddball creations is that they might be too distracting on account of how ingeniously funny they are. In the long scheme of things, that is definitely not a bad characteristic at all!
