A few years back, a friend and I were walking on Market street in San Francisco and noticed a boarded up wall with a small square cut into it. It was as if the small window was begging for people passing by to take a peek inside. To our surprise, there was a bunch of interesting graffiti and a number of people camped out in there. (Peep the barbed wire clothesline!). What was most interesting though was how this scene was directly neighboring the sleek new building below. Such a contrast!
