Angry Scientists

This is Barbara and Dave, all dressed up in their lab coat finery in the Biophysics laboratory. They look a bit pissed off! Only one of them is for real - can you tell which?

I played about with Gaussian blur effects for this one, and I had a lot of fun doing it while I wait for my experiments to finish.

Edit to add: the answer is that it's Barbara who is the genuinely annoyed model! Her experiments weren't working and it was driving her potty. I swear it wasn't the camera she was angry at ;) .
