I am a fan of mosaics and other photo art designs. In my quest for looking for a free software that would allow me to create mosaics, I discovered this fun website, www.bighugelabs.com.
The site offers the user to turn one's pictures into mosaics, pop-up posters, jigsaw puzzles, photobooth photo, mini album/photobooklet and lots more. And what's best, they are all for free! You can even download/save your finished creation and have it printed with your favorite photo printer anytime.
