Himalayan Art.

The purpose of the Himalayan Art Project is to exhibit and catalog Himalayan and Tibetan art from collections around the world with the long term goal of creating a comprehensive and definitive archive.

This is a bells and whistles site but it displays the art well. You can really zoom in on the detail of these pieces. Which is good since they have a lot of detail.
