Via Darren, I came across We’re Not Afraid. While I think the site is borderline profiting from the misery of others, the message is still good:

Show the world that we’re not afraid of what happened in London, and that the world is a better place without fear.

There are hundreds of user-submitted photos, many with people holding up signs proclaiming their lack of fear. If the site is slow, it’s because they have been getting a lot of press recently and as a result tons of traffic, so be patient. There’s also a “We’re not afraid!” group setup on Flickr.
