Some time has passed since our last installment of weird auction fun, so it's time once again to link to some of the most unusual and most bewildering auctions on eBay this week—just for fun.

We'll begin with this ring—er, magick ring—er, bound gothic demon, apparently with the ability to shape-shift and a number of the legions of hell at his (her?) command. It's a bit pricey, but assuming the seller is on the level, it might be an—er—interesting sort of a buy. (Does it come with an owner's manual?)

If you really are looking to buy powerful tools but not the sort that require you to take a ranked position in the armies of the underworld, consider investing in a floating pile driver barge that can be used to insert giant hunks of wood directly into the earth, even underwater. Clean the garage first, though; this thing will take at least one parking space.

Of course the more refined amongst us prefer to wield power of a less obvious, vulgar sort. Demons and pile drivers are fine, but the kind of authority that they grant can hardly be used in politics, business, or Beautiful People circles. For that you need the classics—breeding, genealogy, a family line—or a title. Something like, say, Lord (or Lady) of Tufton or even Baron of an Italian territory. I think.

For the more modern and high-minded, other sorts of power are more interesting. Enlightened souls will find hours of amusement playing with this photon generator, sure to make all of your relativity experiments that much more authentic. Finally, if you're into light but like it more than one photon at a time, consider instead bidding on this very excited-looking tesla coil, sure to make hairs stand on end.

Happy bidding!
