I just found a great cache of panorama images, submitted by photographers from all over the world. I especially like the Prague images:
(Note: All of these panoramas require Quicktime be installed on your system and available for use by your web browser. If they don’t load, then you probably need to just install iTunes, which will install it all for you automatically.)
My friend Dave and I bought some equipment to develop black-and-white photos while we were in Prague in 1994-95. Amazingly, the store where we bought our equipment is a subject of one of the panoramic photos.
