Banksy seems to be everywhere right now. This gaffitti artist/revolutionary just had a big opening in the US and his pieces were going for 100K plus! That is just incredible. His "art" pieces are pretty cool, i'd love to get my hands on one.
But his outdoor graffiti stuff is where it's at. Go to his site and check out what this guy is putting up, especially his stuff from the west bank.
In other art new you can pick up some awesome pieces from the Igloo Tornado collective at their new show in L.A. You can get a little preview from their site Igloo Tornado or from the Losergoes1st site, or here .
