Did you know there's a webcam view of Abbey Road at the crosswalk made famous by the Beatles? I didn't. I've been watching it for the last half hour, waiting for a gang of four to do "the walk." So far, I've just seen some groups of people gathered on the sidewalk; perhaps they're looking for a break in traffic -- it's a busy street!
Here's another of Oxford Street, one of my favorite places to shop. Oh, it looks so springy there today!
This one gives a live view of Piccadilly Circus from the Criterion Theatre, overlooking the Statue of Eros.
This webcam focuses on Big Ben and the Houses of Parliament. Not one of the more exciting London webcams, I'm afraid.
If you happen to be driving around London and want to know what kind of traffic you'll face, check out the BBC's list of "Jam Cams." You have to refresh your browser to get fresh shots of the streets, but it's still a fun way to get a bit of London in your own backyard (or home office).
