Here is a list of 360 degree panoramas I have taken (and pasted together) of various places I have been. Most have been taken by myself, but some have been partially or completely photographed by someone else. They were assembled using Photoshop, and the seams are relatively obvious. I used the free Apple tools to turn it into a QuickTime VR movie.

More recently, I've either used the Canon Photostitch Utility (works great for ones done with a Canon camera in panorama mode, poor for a wide-angle on a SLR). The latest ones were done using Panorama Tools and the hugin GUI, displayed using a Java program called PTViewer. The latest tools are all free and/or open-source.
