In a world full of absolutely braindead high-end audiophile equipment, the Moon Audio Zero Gravity Magnetic Levitation Audio Shelf sets a new standard it uselessness. You see, it's a shelf that levitates using magnets! It's also a $500 shelf.
The argument here is that by lifting your components off the shelf, it protects them from vibrations that will screw up your sound. Of course, I'm sure there are plenty of other expensive devices out there designed to protect your equipment from the harmful effects of magnets, which surely hurt those precious sound waves. Probably also sold by Moon Audio. But hey, levitation! Neato!
