What is it?
It is an application for Mac OSX that basically takes any picture and attempts to create a mosaic out out it using you own picture collections, glyphs and Google Image search terms.
Good idea. Sometimes works. I do give the creators credit because this is a very hard thing to pull off. Fun to use.
Slows down computer, A LOT! Mosaics don't always seem right to me. Takes a while to create.
Free!! (I think)
Here is a picture of it in action:
Its free so what the heck, download it. Its definitely worth a try.
