This gorgeous video was made by improvising a camera-stabilizer on an empty plane seat and shooting timelapse of the squiggles made by the cities the plane flew over. The creator, Flickr user Ettubrute, sez, "On my night time flight back to SF from Amsterdam, I noticed that the lights from cities were making the clouds glow. Really spectacular and ethereal – it was really seeing the impact of urban environments from a different perspective. Each glow or squiggle represents one town or city! …We were around the midwest at the beginning of the clip, and there were fewer cities once we hit the rockies. the bridge at the end is the san mateo bridge."
