Ice cube in daylight

I chose this angle to show that the university library is a cube in shape. I apologise for the tree in the foreground.  Later in the day, we all ended up drinking coffee etc in the library because we had a fire alarm for an incident with brown gas in a lab. It wasn't a fire, but the fire brigade took charge and made sure the place was safe before we got back in.  As a result, one of our people had to go home to Edinburgh on a later train.
