This is a HUGE list of creativity motivators I found on Digg:
--> 110+ Resources for Creative Minds (by Skellie)
Sites include a couple of of my usual favorites (Drawn!, BoingBoing), and then 100 more! I'm gonna add this link to the side bar so it doesn't sink into the archives. Come here if you're in the need of any kind of inspiration, and you'll be sure to find something.
