At Carnegie Mellon University in Pittsburgh, Pennsylvania, Reverend Billy Talen speaks to a crowd about the G-20 summit. Billy travels the country preaching against consumerism, introducing himself as "the Rev. Billy from the Church of Life After Shopping."
For a more distant shot, see http://gigapan.org/gigapans/33527/
To read Rev. Billy's writings: http://www.revbilly.com/chatter/blog/2009/19/a-peace-activist-thinks-about-g-20
Photographer comments: I should have locked exposure on the camera. 2/3 of the way through the shooting, as the robot & camera panned from left to right, Rev. Billy finished his speech and the crowd started to disperse some.

Carnegie Mellon University freshman Sarah Ceurvorst and other students created this huge sign near the CMU track. Ceurvorst said "We need to come together, find common ground, and aid each other in our time of need. 'Help Wanted' means that we do not need violent protests that will only cause chaos and fear. We need to remember that the G-20 is about coming together to try to find a solution to some of the world's major problems."
Photographer comment: I should have locked exposure on the camera.

Photographic notes:
Stitched at 50% resolution.
This gigapan has problems:
The memory card filled up about 90% of the way through shooting, and when I set up for the final 10%, the camera's zoom had changed.
The memory card that I used for the first 90% must have been slow, because occasionally it would fail to write the image file, so some pictures in the grid got dropped. I wrote a Python program that looked at the time between pictures to help me locate the gaps, and filled them with a blocky gray photo. Without that I never would have been able to stitch this at all.

Rim Road climbing area, McConnells Mill State Park, 45 minutes north of Pittsburgh Pennsylvania.
Some geology: before 140,000 years ago, rivers in this area flowed north toward what is now the Great Lakes. During an ice age, lakes built up along these rivers behind the glaciers that covered much of North America. One of these lakes rose enough that it spilled over a watershed divide near here and started to drain south. In a dramatic geologic change, the drainage of several huge lakes over a short time scoured a gorge over 400 feet deep here, resulting in the current Slippery Rock Creek. This creek today flows south and west toward the Mississippi River.

We shot this from Mt. Washington, looking down at The Point (where the Monongahela & Allegheny Rivers join to form the Ohio), from which the fireworks were launched. Our panorama includes glimpses of the crowds at The Point and in the Northside (near the stadiums).
We shot two panoramas in quick succession and chose selected images from each set to put this mosaic together. Including the crowd around us in the picture turned out to be a good decision, I think.

pull down on the handle and the (heavy!) gate lifts up, unblocking flow in the channel. The lever arms have counterweights (hanging, or welded on) to make it easier.
Operating these must have been a hellish job.
