If you thought that 45 gigapixel panorama of Dubai was something, you ain't seen nothing yet. This 70 gigapixel shot of Budapest is so massive, you can zoom right into the windows of those apartments on the horizon.
The panorama required two 25-megapixel Sony A900s, 400mm Minolta lenses, and two days each of shooting and post-processing. That's all well and good, but you'll mostly want to focus on the zooming in and out part. Which you can do, for hours on a summer friday, here. [70 Gigapixel Budapest via Engadget]
