Shape Collage is easy to use and the results are so cool that you’ll probably get addicted (as I did) to making lots of collages based on shapes and pictures just to see how they turn out.

An artsy option, this gallery-style collage frame holds nine 4-by-6-inch photos. The round shape gives the frame a sophisticated edge, which means it can also serve as the focal point of a room.

If you’re a collage fan, you’re probably familiar with Shape Collage for the Mac (3.5 of 5 rating). Well, there’s also a $2 version that you can tote around for both the iPhone and the iPad.
