Don't worry, I'm not going to hug you. Hugin is a freely avaiable for non-commercial use program used to stitch photos together to make a panoramic view of said photos. Feeling inspired by AJ's picture, I tried to take a picture of a huge rainbow last night. I couldn't get the entire rainbow in frame, so I took several pictures of it.
Using Hugin, I was able to create a panoramic view of the pictures I created with in a few minutes.
Hugin is available for download for Windows, Mac, and Linux.
