Tile-R is a simple, but very interesting iPhone App. It uses your picture to make a set of tiles. You can adjust it to make as many tiles out of your picture as you want. While experimenting with it, I came across one tile of a picture of me that struck me. I know that you can crop the same thing. I think what I like about it is that I wouldn't have normally sliced the pictures the way Tile-R did it. I think it's cool. How about you? Incidentally, it's free.
