Maybe you’re a geek and you now feel going back to a simpler time, recalling that your momma wasn’t keen on the idea of having a pet rock around the house. It’s payback time.

Heard of tektites? Tektites are for you. They may be ugly-looking naturally occuring rocks (sold around at prices depending on size, clarity, color, and rarity).

What makes them interesting, though, is that there is no good explanation as to how they came about. The best science can offer is that they are remnants of meteorites and that they come from the moon.

So how does a pet tektite fare with, say, an iPhone? Well, as a cellphone, it’s not yet wifi-ready, it doesn’t yet play mp3, and it can neither yet receive calls nor make ones. The consolation is that it can actually be carved into jewelry. There’s also a claim that holding a piece of tektite recharges your energy and enhances your psychic abilities.
