I love Facebook and Twitter competitions and recently won a photograph of the Olympic rings at the London Bridge by Peter Paredes.
I've known Peter a bit through Twitter and besides being a top London photographer he is also a fun person to keep in contact with regarding any topic.
Follow him on twitter or visit his website for some photographic goodness.

Thanks for the photo Peter as it works real well as a memorabilia of the Olympic games.
