Memorylage

A beautiful new way to view your photos, Memorylage presents your entire photo collection as giant collages, built on-the-fly every time you view them. You can then select your favorites to create new collages to share, or use the Photo Booth feature to take new pictures.

You can also create collages custom-fit to your phone, and then set them as your lock screen. The bottom can even be dimmed to make it easier to read text over a lighter image.
