Foto-Mosaik-Edda Makes Magnificent Photo Mosaics
You know those posters that have an overall image, but if you look closer, that image is made up of hundreds of tiny photos? It's called a photo mosaic, and Foto-Mosaik-Edda is a free program that will generate them for you.
Start it up and point it toward a large photo collection. A few thousand photos is a good minimum. Add them to the database, then choose a single photo to make into a mosaic. That is what all these photos will be arranged to look like. You can fiddle with the photo density and many other options, then Foto-Mosaik-Edda gets to work.
It takes several minutes, all told, but the end result is an impressive high-resolution mosaic, suitable for a poster if you take it to Kinko's. The app even includes a simple photo viewer that easily zooms in and out, so you can see each individual photo as well as the entire mosaic.
Foto-Mosaik-Edda is free, and it does exactly what it's supposed to do, and well. If you've got a ton of photos of your kids, and want to give a relative a one-of-a-kind gift to frame, give Foto-Mosaik-Edda a spin.
Note: This program is donationware. It is free to use, but the author accepts and encourages donations towards further development. The first eight times you start up, a five-second nag screen asks for a donation.
