Caleb Larsen's "A Tool to Deceive and Slaughter" isn't quite as menacing as its name makes it out to be, but it's definitely a flighty little fellow: it continually creates new eBay auctions for itself via a built-in Ethernet jack.

No owner is quite good enough for this big-headed piece. Larsen's "Tool," a shiny, black cube with an Ethernet jack, pings a server every ten minutes to determine if it is listed for sale on eBay. If it's not, it creates a new auction. Mind you, this isn't only a conceptual function of the piece; it really is constantly auctioning itself and being purchased by new owners. You can view the current auction at http://atooltodeceiveandslaughter.com/.

The going price for the current auction, ending in five days, is $4,250. The piece has been in circulation since 2008.

"A Tool to Deceive and Slaughter" isn't for art collectors with fragile egos. It will leave you. Unless, of course, you forget to plug it in. [Caleb Larsen via Make]
