We spend enough time in the US that I can redirect my loathing of too-early Cashmas decorations into the more socially acceptable comment that you should wait till after Thanksgiving.

Regent Street didn't wait; the lights went on the evening we went to see The Bourne Ultimatum on HD DVD. I knew what they were going to look like because I'd already written them up but it was nice to see them in action. They're collections of LED spheres that change colour and flash on and off in response to people walking past, light levels, wind, temperature... When the Nokia Store opens next month I shall pop in, not to look at the phones but to press the buttons in the window that let you control the lights. Kinda cool...
