The Austin street art -- murals, slaps, wheatpaste posters and the like -- is awesome.
And the Hope Outdoor Gallery is like a street art mecca. According to their website, this space launched at the 2011 SXSW with the help of Shepard Fairey. It appears they would like to have some control over what goes up, but there seemed to be plenty of non-sanctioned painting happening.
They're looking for a new home, since this spot is destined for development. I hope they find a good spot! It was so cool to see layers of art, and even cooler to see people hanging out and appreciating this space.
