Customize your collage with Shape Collage

I'm a big fan of Zykloid Software's Posterino, a Mac app that allows you to create elegant collages. Similarly, you can use Shape Collage to create a collage. However, as implied in the app's namesake, you can also customize the shape of your collage to one of the many included preset options, as well as your own customized shape. One example would be pictures of hundreds of shoes in the shape of the Nike swoosh logo -- you get the picture.

While the app is billed as "free," the free version stamps a watermark that, while small and light, is nonetheless noticeable. US$25 removes this watermark, and adds the ability to export to an Adobe Photoshop PSD (where you can manipulate photos).

Shape Collage was created by developer Vincent Cheung, and is available for download here.
