Wow. Here's some incredible pictures of the anti-inauguration protest in DC yesterday (link is to first photo in series). My favorite.
It's also the best implementation of the "click the left half of the picture to go to the last one, or the right half to go to the next pic" thing I've been meaning to do with my own photo gallery. It's inspired me to finally implement that myself. I'll probably model it directly on theirs, because it works very well.
