Fountain at Heathrow Airport

We arrived at London's Heathrow from JFK at mid morning today. After at least an hour in the passport line we collected our luggage and boarded a bus to Gatwick Airport (a bit over an hour's ride to the south). I took this shot from the bus at Terminal 5, a considerable distance from Terminal 4 where we had arrived. The fountain sends multiple spurts of water into the air at intervals, to various heights and in a whole series of different configurations--we observed it for at least ten minutes and it never repeated. (Details are much better in large.)

We're staying in a hotel at Gatwick and take a plane to Portugal tomorrow for a week's birding tour with a group from Naturetrek--our first ever in Portugal
