There are approximately thirteen million CCTV cameras in the United Kingdom. They are use to monitor people for security reasons--not all the time, though. A band called The Get Out Clause played their music in front of eighty cameras, requested the footage citing the Freedom of Information Act, and put together a music video. This story is about a year old, but I thought it would still inspire entrepreneurs to think outside the crosswalk. (Thanks to Mordy Golding for telling me about this.)
