Many wikis out there use icons, or artworks, to wiki layout and/or presentation. For example (my apologies, only french links provided):

• http://fr.wikipedia.org/wiki/Accueil
• http://doc.fedora-fr.org/wiki/
• http://doc.ubuntu-fr.org/

One good start would be to investigate what kind of icons we would like to have in our wiki:

• any work previously done, or WIP, from TNF or marketing?
• define conformance to NetBSD's graphics standards?
• reusability? (licences, public domain vs CCs vs GNU derivative work, etc.)

Inspiration: see icons from wikimedia.

You've seen this, but others may not have: ikiwiki comes with some built-in icons we could be putting to better use. --schmonz
