I meant to note this earlier but am just remembering to do so. Yuval Ben-Ami has been doing an interesting ongoing photo essay at +972 Magazine, the liberal/dovish Israeli site, documenting a trip around Israel in its 1949 borders. The whole thing is called The Round Trip, and its posts can be accessed here. Great photography and astute political and social observations. As of this post he's gotten to Eilat in 18 stages and still has a way to go. A good sample is his post on following the old dividing line through Jerusalem.
Do take a look; if you know Israel or just want to know more, I think you'll find it worth the time.
