I just completed the last of a two part assignment for my class. It's kind of cool, so I thought I'd share.
The original picture
The first assignment was to cut and paste using the selection tools we learned about in class to assemble the puzzle.
The second part of the assignment was to use patch, clone, and heal to get rid of the lines and recreate the full photo of the cabin.
Pretty neat, huh? I can still see a few places that could be blended a little better, but to the untrained eye its pretty amazing what you can do with this program.
