I noticed that too, I can't wait to see it lit up. More colour on our skyline is a good thing in my books. It's a shame BA didn't have LED's lighting up the fins at night, even a soft blue would have been handsome.
When I walked by RBC this morning the LEDs had been turned on on the north elevation of the tower, but only on the western side of the inset. They were tuned to white so they weren't really noticeable, but they were definitely on
