I just found this free program this morning; I’ve downloaded and installed and played with it a little. I’ve got more playing to do, but I’ve seen enough to believe this is a good one!
I subscribe to the RSS feed of Gizmo’s Freeware, and today this program was featured. It’s a free utility that creates mosaics from other photos – you’ve surely seen these on various television shows – a picture that when it’s zoomed in upon, turns out to be made of thousands of other pictures.
Since it’s not nice to totally paste content from another site, I’m going to link to the site here - go take a look and see if this is something you might want to try. Unless you are just completely uninterested in playing with your digital photos, I think you’ll be pleased with this one.
