Well, you knew I'd end up doing something like this. :) I had thousands of pictures that I didn't use during my Picture a Day for a Year project, and HAD to find some way to use them! This picture was made with 3,270 images taken during my project. The final picture has 4,240 little square pictures in it, so you'll notice some of them show up more than once. All the little pictures were taken by me during my PaD year. The full sized version of this picture is a bit bigger than this and it prints out quite clearly at 20x30 inches.

I figured I'd post it here to give the rest of you one more idea of what you can do at the end of your project. Enjoy! Oh yeah, one other thing. The software I used was Centarsia.
