Giga Pan

Image

Here is a photo taken using a panorama image capturing device called gigapan created by the carnegie mellon university and a canon g10 camera.
The photographer had to click 220 snaps from that camera to get this complete view of the Obama's inaugural address. It took a macbook pro around 7hrs to process the complete image. The final size of the image is over 2GB.
