I had to Google Harrod's displays that Mitchymoo mentioned. Way cool. I think this was 2013.
I'll take 3 London Eye Ferris Wheels, please... to go.
You can Google Harrods to see all current and past window displays.
Have you noticed too in the opening montage scenes of the BBC's Sherlock, how they show the city of London in a shift photo making it look miniature? Love it! CM
