Lately whenever I am in need of inspiration I have been visiting CGSociety. As the name implies most of the work is from 3d artists, and other digital media. With my current interest in Blender this is the perfect place for me to get inspired, and maybe learn some new skills. I find the articles about the behind the scenes of videogame creation especially interesting. They show how much artistic work goes into the development before the finished product hits the stores.
So the next time you are in need of inspiration check out CGSociety.
