Keith and I made this penguin using the free program Andrea Mosaic and a library of 6000 of the photos we've taken since we started dating.
To see the 1000 photos used in this mosaic in more detail, open the photo in a new window, or save it to your desktop.
There are no duplicate photos in the mosaic, although there are similar photos used more than once. When using your entire photo library, you will find that the over/underexposed photos that you've saved come in handy as the program tries to build your mosaic. (The photos in this mosaic are 100% unaltered.) The program also seemed to like scenery pictures from our trip to Hawaii and photos from Free Parking concerts.
