Giant Robot's Tree Show 2 is not to be missed. The Upper Haight Gallery (affiliated with the popular art magazine) asked a bunch of relatively unknown artists to create works on the tree theme and has pledged a portion of the proceeds to Friends of the Urban Forest. We love shows like this because it's fascinating to see the variation in responses to the theme. Yes, everyone loves trees, but for some that love translates into cheeky graffitti; and for others, whimsical reverie. Tree Show ends August 24th. The works are viewable and buyable online as well, but visiting them this way only doesn't give you a chance to experience the impressive delicacy of Beci Orpin's wood cut.
