PAPER Digital Renegade Aaron Koblin and director Chris Milk have recently teamed up with Google and London's Tate Modern museum to create a neat collaborative online art project modeled on the "Exquisite Corpse" -- the classic palour game in which a group of people create a sentence by having each person add one word or phrase at a time, not knowing what the other preceding words are.  Riffing on this idea, Koblin and Milk have produced what they've dubbed "The Exquisite Forest," an online program that takes short animations created by Tate Modern artists and uses them as a launchpad for visitors to then create their own, building and expanding on similar themes so that the animation sequences flows out like the branches on a tree. For a better idea of what all this means, watch the video above and, if you live in (or will be visiting) London, check out the physical installation, which arrives at the Tate on July 23 and will run for six months.
