As with any landmark, one trick to coming up with an original take is to focus on details. Even then, it is likely that there are a few dozen (or more) images that might look quite a lot like this one.
These are lght fixtures on the Golden Gate Bridge. The curved ones pointing down provide lights at periodic intervals for pedestrians and cyclists during evening hours. The ones pointing up only appear near the towers and presumably light those features at night. This is a simple HDR from 3 exposures handheld on my Olympus E-PL1.
Processed with some basic Nik Filters (Pro Contrast and a brushed-in Tonal Contrast) and finished off with the Cartooned Preset from Topaz Clean.
