I started a 100 strangers type project recently, nothing massively original and I've still got a lot to learn but other people might find it interesting. This is one of my strangers; Aziz. See the blog here: http://stratfordroadproject.wordpress.com/
I like this idea.. the kind of thing you would see as a small exhibition in an art gallery, and well taken pictures. Good if you're comfortable approaching people like that! Do many people say no?
