photomosaic's are cool...
But they work best as an addition to other collages...

You could attach the photos to an object via photoshop. Then add other things on also..like post it notes or a keepsake. My best suggestion would be to use a bulletin board as the foundation. Do thye use bulletin boards in other countries?
I just read the things white people like' thread, and now I'm paranoid x___X
