Coca-Cola turn their HQ into worlds largest screen
For their 125th anniversary coca-cola turned their HQ into one huge light-show. They hired a company called Obscura Digital to turn all 4 sides of their Atlanta HQ building into a giant 26 story tall projection screen. All in all that amounts to over 200,000 square feet of projection surface. The setup also appears to use multiple projectors on the ground for each side, seamlessly lined up to create one giant animation.
