Ghost Lamps from designer Tim Baute look like they're hovering. Plus, unlike most shit you see that's cool, they're actually available for sale ($250 for a small, $275 for a large) and go perfect with a Ghost Table. Just don't ask me how the illusion works. But if I had to guess I'd say it has something to to with anti-gravity lampshades. Or sorcery. Probably sorcery (I applied the scientific method).
