Lanxon writes "How much would you pay for a piece of artwork that you could only own for a week? A Tool to Deceive and Slaughter, 2009, is a black acrylic box that places itself for sale on eBay every seven days thanks to an embedded Internet connection, which, according to the artist's conditions of sale, must be live at all times. Disconnections are only allowed during transport, says the creator, Caleb Larsen. Larsen tells Wired UK: 'Inside the black box is a micro controller and an Ethernet adapter that contacts a script running on [a] server [every] 10 minutes. The server script checks to see if the box currently has an active auction, and if it doesn't, it creates a new auction for the work.'" Another condition of sale is that the artist gets 15% each time the piece is sold. Maybe the First Sale Doctrine works differently in the UK.
