Hmmm. Mental assylum escapees? Good shot. I like the composition as the angle adds to the weirdness of the scene. I am guessing that they are feathers or pillow stuffing in the air?

Some kind of outdoor dance performance. From what I see here, I wish I had been *there*. Great relevance and impact. This looks like it may have been taken some years ago on color negative film, translated into b/w.

Is making people hold their heads sideways the in thing to do in photography all of a sudden? I'm sorry to say, I really hate that.

That being said, this appears to be some sidewalk acrobatics. I saw something along these lines in Barcelona.
