Sahihi has two great photo exhibits going Women in the IDF, and The Drug Series. Both are completely work safe, BUT backing up to the Index page out of either of these two links will bring you in contact with some work that is questionable.
Women in the IDF is a collection of pictures showing normal everyday women toting machine guns and a smile. It is both captivating and disarming.
The Drug Series is interesting. Sahihi captures facial expressions from drug users, each drug/user is subtly different.
