Thanks Djohn. I don't think that I stand much chance of winning anything :-( People had solved all the Box 3 puzzles before I'd even started this morning!
We did go to Trafalgar Square last night hoping for a decent spectacle - after all Las Vegas got a film projected onto the Belargio fountains, the cities hosting the 2nd box clues got sky-writing.... all we got was a picture/pattern projected onto the National Gallery. It wasn't even a very spectacular picture: the other cities hosting Box 3 clues got much prettier displays.
There was no sense of occasion either: it was supposed to happen at 7pm but the picture was already being displayed when we got there. We hoped that maybe at 7pm something else would happen ... but nothing.
