A quick post to let you know that TurboCollage - Collage Creator - SilkenMermaid for the Mac is FREE in the Apple Mac App Store for today only.
The app allows you to create collages with your photographs in various ways (using a picture pile, picture grid, mosaic, center frame, and a zig mosaic).
It is highly rated in the Mac App Store. I've used it on some projects and had been pleased with my results.
