The Times has an image from the air:
You can spot the Tea Party rally in the park area near the capitol columns. As Breitbart and others spoke, the unions paraded around the square in brightly-colored T-shirts and hats. Inside of the capitol, students, teachers, and activists danced and yelled for hours; I spotted a few doing yoga. One circle of long-haired undergraduates played little jams on guitar and didgeridoo. Many slept inside of the capitol and remain there this morning.
