At the Consumer Electronics Show, Microsoft flaunted a video wall at its booth that stretched a respectable 70 feet (21 meters) long. The folks behind it - Mind Opera, PBJS and Run Studios shared some behind-the-scenes stats along with a nice video of their work for both the exhibition pavilion and the keynote backdrop.
