AIGA Gallery

http://portfolios.aiga.org/

This website has numerous gallery topics.  Just select a topic you want to see (ceramics, computer animation, music, etc.) and it will bring up every image/video/project they have on the topic.  If you really like a specific work of art you can go to the artists information page on the site.  It gives you basic information about them, more of their work, and a link to their personal website if they have one.
