Here's something you don't see every day. I was on my way to work, walking past a branch of Barclays bank that had highly reflective glass windows, and I spot a group of about 10 people simultaneously taking pictures of themselves in the reflection. I just managed to step in while there were five or six of them left and take my own snap.

I've done a few Mirror Project searches to see if any of the others in this picture had submitted their own images but have turned up nothing. A shame, as it would've been interesting to see the same reflection from the perspective of each photographer.
