I like this time-lapse video (embedded below) of a flight across the US. ((Transportation-related gem from several years ago: a video of a man driving from LA to New York. For more time-lapse videos, see this collection over at World Hum. My favorite is this time-lapse video of the northern lights))
The clip begins in the US’s midwest and ends in San Francisco. According to the person who created the video, the light from the cities below was illuminating the clouds.
