PAG Awards
Offers two for art related sites. One with three levels (Gold shown) that are given to recognize artists and to promote art in general (no porn). There are rules but they are closer to the feeling than the material.
The second one is only given to exceptionally beautiful sites on the web. Sites that go above and beyond both in design and content.
The purpose of the PAG Web and Art Awards is to give recognition to artists and web designers who have mastered the art of superb web design and/or achieved a professional level of artistic expression.
