If you use Debian and want to get some great free truetype fonts, just type:
apt-get install ttf-aenigma
There are over 400 free fonts in that package. Awesome.
Speaking of debian and free art, there is another package called openclipart-svg I'm going to check out. There is a site for public domain clip art too:
http://www.openclipart.org/ - this is a great project, with people now sending out legal threats based upon clip art, its good to have a centralized clearinghouse of open source clip-art.
UPDATE! More fonts:
apt-get install ttf-alee ttf-tuffy ttf-summersby ttf-radisnoir ttf-manchufont ttf-konatu ttf-fifthhorseman-dkg-handwriting ttf-dustin ttf-f500 ttf-ecolier-court ttf-engadget ttf-inconsolata ttf-isabella ttf-beteckna
