If you've ever wanted to put together a series of shots into a panorama, you might want to try the free Autostitch program. It's the result of research from the Artificial Intelligence lab at the University of British Columbia. Yes, there are a number of photo stitching programs to create panoramas out there, but Autostitch is unique in that you simply feed in the photos to use, and it does the rest - no human intervention required! They have a free demo version online that you can download and play with to your heart's content.
