Yorkdale Mall in Toronto, runs a light show somewhat similar to the Freemont Experience in Vagas.. albeit, not at all the same quality. During the 2007 Christmas shopping season, the light show runs every hour from 6pm, and syncs music to giant lighted stars dancing on the ceiling. Unfortunately, I was shooting the vid with a small Canon still camaera in video mode, so the audio is not the best.. made worse by the morons beside sitting beside me who just would not shut up. Reportedly, there are 700,000 lights (LEDs?) that make up the display. (less info)
