I have a feeling that people who like art museums have never looked at concept art for movies and video games. Commercial art is so much better than the arbitrary crap they put up in museums.
Just learned about this website: CgHub.com, which “focuses on artists in the entertainment industry, primarily movies (visual effects), television, commercials, animation, games, and illustrators and sequential artists (comics).” I could have been one of them, but photography ruined my life.
And if you’ve never been to DeviantArt.com, be sure to check it out. That’s where I get all my desktop wallpapers.
