Nokia has been going all out to promote the Lumia Windows Phone 7, the pinnacle of which was is in London, UK, back in November as a huge animation projected onto the 120m high Millbank Tower on the banks of the River Thames. Each of the tower's 800 windows were covered with vinyl, while 16 powerful projectors on the other side of the river beamed images onto it. I am really interested in finding the specs of those projectors!
