If you’d like to do something different with your digital photos then most image editors provide at least some artistic effects you can try. They’re not always that interesting, though, and after you’ve tried ten “Oil Painting” filters which don’t produce anything vaguely painting-like, it’s tempting to just give up. But wait: there is another option.
AndreaMosaic is a free tool for creating photo mosaics, pictures which are themselves built up of other images (check the program samples page if you’ve not seen these before). The technique only takes a few minutes to master, but delivers pictures with an appealing, abstracted look, which look great on anything from a Facebook thumbnail to an A3 page (or even larger printed formats).
