Picasa does awesome mosaics.

Re: [gentoo-user] [O.T] photomosaic
Hi everyone, One can use Image Magick for building multi-images mosaics with command-line tools (minimum CPU load). Get Image Magick : http://www.imagemagick.org/ How to use it for building mosaics : http://www.cit.gu.edu.au/~anthony/graphics/imagick6/mosaics/ Hope it helps, R. Boumghar.
