I’ve been playing around with fotowall (Already in Fedora’s repository!) for an article I’m working on for opensource.com, and while I was messing with it, I ended up making a nice collage out of the hundreds of screenshots I took for the Liberated Pixel Cup Games.
Clik here to view.

Normal resolution is available at 1366×583, while High Def has a 1920×1080 resolution and HD Plus has a 1920×1200 resolution.. I’d be happy to make different screen resolutions if requested.
Since fotowall currently doesn’t collate images, and when you add them, it stacks them in alphabetical order… I ended up investigating about a way to randomly add the files.
mapfile -t -n 48 files < <(find . -type f | sort -R) && fotowall ${files[@]}
mapfile helps create a random array of files, which is then passed on with the ${files[@]} argument to fotowall. Neat, huh?
