Microsoft is doing an odd promotional event in Manhattan's Herald Square today. Basically, the company built a huge Windows Phone. It's four stories tall, and by my shaky a² + b² = c² calculations, the screen is around 60 feet diagonal, with a pretty non-standard 1088 x 616 resolution. At different times throughout the day, one of the huge tiles folds away and reveals a live performance — fitting for the near proximity to Broadway. I wasn't distracted by the flash and pizazz, however, I wanted to get to the bottom of this thing. Also, to the top. Microsoft's Aaron Woodman gave me a tour. Check out the video below, as I venture... inside a giant fake Windows Phone.
