Last night I tweeted that the high clouds in the sky could make for an interesting sunset. So I set up the iPhone and made a time-lapse movie of the sun going down behind the Chicago skyline as seen from the John Hancock Center (875 North Michigan Avenue).
Unfortunately, the clouds cleared out just as the good colors were coming on, but you can still see its light making rainbows in the ice crystals.
There are a couple of times when the picture jumps. Those are when someone called on my phone. Oops!
