One of the mashups on Flickr that interested me was Montagr, which uses photos on Flickr to create mosaics. You can type in a word, for example 'flower' and Flickr will show a photo of a flower and then proceed to create a montage replica of this photo from other photos of flowers in the Flickr collection. You can then click on each individual photo as well. The idea of creating these mosaics is creative and imaginative and can be beautiful. I can't see any terribly practical application for it apart from creating amazing images, but perhaps that is a sufficient end in itself. Anyhow it shows that people out there are coming up with new ways of using technology all the time.
