London-designer Asif Khan's pavilion for the Sochi 2014 Olympics is essentially a building-sized pin screen, capable of transforming its facade into 3D projections of visitors' faces. Khan designed the pavilion for MegaFon, the general partner of the Sochi Winter Olympics and one of Russia's largest telecommunications companies. Visitors can have their photo taken at 3D photo booths stationed around the pavilion and throughout MegaFon retailers preceding the games, and then watch the facade shift into gigantic portraits.
Khan also designed the Coca-Cola Beatbox Pavilion for London's Summer Olympics in 2012. Check out a test-run of the pin screen in the video below.
