It's Social Media Week (13-17 February) and Nokia, the global headline sponsor, has a few magic tricks to show off using Lumia Windows Phones. They hid two magicians, Matt & Prakash, in a secret trophy case accessible only by using Foursquare at the opening event of the Social Media Week.
This fits in nicely with Nokia's promotion on this side of the water, using London black cabs. Check out two more clips after the break, note that the third magic trick doesn't exactly use a Windows Phone as a prop.
