The great Man ray in two cool sites: Man Ray Trust and Man
Ray official digital photographic library. The first more stuff about him to buy. The second site hundreds of photos and other works or Man Ray. Interesting sites for people that like cinema, art, photography or beautiful images. (via Quando, Onde e Como)

If you don't know his surrealistic work in cinema I suggest three short movies that I saw: Le Retour à la raison, Emak-Bakia and L'Étoile de mer. And more links about Man Ray: American Masters - Man Ray; Man Ray on Getty Museum and Man Ray by Wikipedia.

Update: Sean from Bitter Cinema found a wonderful site where you can watch the Man Ray short movies Emak Bakia, Le Retour à la raison and L'Étoile de mer.
