I'm not sure if this is the correct section in which to post this, so here goes..
I like to change the desktop wallpaper on my computer quite often and I have the two tartans for my clan. What I'd like to find is a downloadable archive/zip/tar file that includes all known tartans, I could make a screen saver out of this too. Does such a thing exist? Where might I find this type of thing?

I know there is a program you can buy that will run on a Microsoft Windows machine, but I don't use Microsoft products.. I use Linux and have been happy with it since 2001. Just a set of computer generated images would be great, I can do a lot with these.
