Nokia's going all out to promote the launch of its Lumia 800, and it's hired deadmau5 and a team of light projection specialists to put on a 4D show tonight at London's Millbank Tower. Images will be cast on the tower's 800 windows, and streetlights and buildings nearby will go dark to enhance the effect. It's a half-hour show starting at 9PM GMT / 4PM EST, and you can watch a live stream of the event on Nokia's Facebook page. If you can't make it to the event, Nokia will also be throwing the show up on some big screens in Swansea, Middlesbrough, Coventry, Swindon, Dover, and Portsmouth. Sorry, non-UK fans, the live stream's your only option.
