Yesterday we revisited Sol LeWitt's altered aerial of "part of Manhattan," and while pondering the definition of art, we got distracted by other aerial images of New York City... particularly the vertigo-inducing ones. Here are five photographs that will give you that special feeling of dizziness (if you're into that sort of thing), plus one bonus image for reverse vertigo (if that even exists).

Of course, you can't talk about vertigo without recalling Alfred Hitchcock's 1958 classic film starring James Stewart and Kim Novak. Hitchcock used the dolly zoom to represent the sensation of vertigo—check it out in the trailer below.
