The Exploratorium has a pretty cool roof cam. It is set to shift its view every fifteen minutes, or you can select from several presets.
If several people are visiting the site at the same time they queue up to take turns controlling the camera. When you are in control of the camera you have the ability to scroll right/left and up/down. You can also zoom out or in, between 1x wide angle and 25x telephoto).
The presets include:
Golden Gate Bridge
Wind Surfing Area
Golden Gate Bridge Approach
Palace of Fine Arts Lagoon
Weeping Women at Palace of Fine Arts
The Exploratorium’s Weather Station
Another Bridge View (this is the one shown above)
And the Wave Organ (an Exploratorium project with artist-in-residence Peter Richards)
