Lightopia 2010

One of the more spectacular of Tokyo's illumination shows, consisting of light-based art installations, an 'ambient candle park', and something calling itself a 'flower fantasia'. Sarcasm aside, it's a beautiful way to light up the dark winter night, and the Marunouchi streets are all the better for it. It's free, too, which will delight any Scrooges looking to warm their cold hearts.
