Aeolidia recently redid their site (they are awesome web designers), and they had their artists create new illustrations for them.
It's an underwater theme. By the way, the white things are sea slugs, Aeolidia papillosa a.ka. the shaggy mouse. It's a nudibranch, which is French for "naked lung," and also one of my favorite words, along with "atlatl" and "mukluks."
Anyhow, if you go to their site, you can see all the new illustrations. There's a nifty theme switcher doodad that will allow you to see all the artists' work.
