apologies if this has been posted before.
the above device/installation artwork piece, titled a Tool To Decieve and Slaughter, sells itself on ebay every seven days. It is an acrylic cube with a computer inside it. As part of the sale agreement, the new owner promises to leave it hooked to the internet whereupon it puts itself on ebay. it originally sold for $2500, i think this week's auction, the third or forth in it's life, is sitting around $6800. The owner keeps the proceeds less 15% of each sale remitted to the artist.
originally i thought this was a mockery of the art world, but it does seem to be brilliant art marketing...
