Looking out the window last night I was immediately struck by the enormous blue lit rectangular glass box on top of Tabard Tower. It hides the water tank and the window cleaning contraption. Have to wait for tonight to see if it's going to be a permanent illumination. Looking out the kitchen window on the other side is the blue lit Tower 42 (formerly NatWest). I suppose being bang in the middle we are protected from low flying aircraft or UFO's. That's a relief anyway!
