Mashups mosaics and mmm...?

Mashups I relate to a kind of collage - too messy for me, I like minimalism. In Big Huge Labs I checked out fd's Flickr Toys and liked in particular Mosaic maker which I felt was something I would most likely do with family or travel photos. I found a wonderful mosaic of Obama (Barack) and now I can't find it any more - oops - so I haven't got the actual link to it. Top cameras I liked because I found mine there, Trading card I may also use and Jigsaw could be fun too.
