Must be a good App!

A bit spoiled for choice today. I had some shots of the Cutty Sark including one taken from underneath. A few nice shots of the Royal Naval College at Greenwich. And had someone trying to persuade me to use the one of a bassoonist playing Ravel's Balero.

However I was intrigued by this group who were taking part in a promotional film presumably about people ignoring each other totally engrossed in studying whatever they have running on their devices. It's actually a very common sight these days.
