I've talked a lot about how IT administrators should take all the free clip art they can download, assemble it and categorize it, and give it to every user to make OpenOffice.org more fun and more usable. I have pointed to the clip art (see the new list at the left side of this blog page about free clip art, templates, and fonts) but have yet to specify how to do it.
Step 1: Download massive amounts of clip art and categorize it. If possible, get an intern to do this.
Be sure to categorize it in separate directories as you download it -- or after, if that works better for you.
Step 2: Figure out how it all works, conceptually.
