Wait till you see this - it blew me away. I can't even remember how I came by this site, but once I got there, I couldn't leave. The result of viewing these 360 degree panoramas left to right and top to bottom are mesmerizing.
You can view one of my favorites right here. Check out the main site for about 50 more 360 degree panos right here. They take a minute or two to load. It's worth it, give them the time to load then hit your mouse and take a magic carpet ride though the image - very cool.
