Mosaickr takes advantage of all of the Flickr photos that you have in your account and transforms them in to a mosaic. The service is totally free, but they will charge you if you want to print it out as a poster. Overall, MosaickR would certainly make an inexpensive and thoughtful gift that would really impress someone, or you can just get one for yourself because it’s really cool.
