Last year I visited San Francisco and loved it. The Vimeo blog recently featured this stunning time lapse from Simon Christen. Simon spent two years trying to create this: and it involved waking up at 5AM, looking at weather forecasts, and loads more planning. There was also lots of failure involved where the fog would be too high, too low, or gone sometimes.
But it all paid off quite well for him. Take a look and prepare to be astonished after the jump.
