Curvature of the Earth

Just what the title says, it's the curvature of the Earth! I took this almost a year ago, on a trip to Vancouver. I took it from the plane, 'cause I was awesomely lucky and got a window seat. I'm actually at =changingseasons's house right now for a grad party thing, and I was browsing through some photos on my laptop, and I found this. =changingseasons and ~Xeniphyst both thought it was a nice pic, and I figured I'd post it.

=changingseasons came up with the title.
