SXSW brwsr is a quick browser of images posted on Twitter tagged with SXSW. Those attending the SXSW conference, as well as those who could not come (like me) can enjoy the stream of pictures.
Hacked together thanks to jsFiddle.net and APIs made available by Twitter, Instagram, Img.ly, YFrog, Twitpic and twtgal.
Designed for iPhone mostly, so it may not look very nice on large screen...
