One of the funnest, most dynamic projects to come out of the (official and unofficial) inclusion of art installations in SXSW is the Impossible Wall Project. A collaboration between graffiti groups Pow! Wow! Hawaii and our own SpraTX, the event brings together artists from all over and gives over a public space to each to create his or her mural over the week of the festival. Here's some of their work (some still in progress), a little festival bonus they left behind.
