From Kevin Neelands:
Use this app to quickly and easily create kaleidoscopic images from pictures you have or have taken with your iPhone. YOU select what segment of a picture to repeat, how many times it is replicated, and whether or not adjacent slices are "mirrored". Interesting and unique designs can be made from faces, and even poorly taken photos lend themselves to a magical transformation in this virtual kaleidoscope. Don't just send your friends emails of snapshots of their faces - send then wonderful spiral patterns based on their likeness that you create in a matter of seconds!
