Turns out the Lehman Brothers led display is modular. One morning I’ve seen the maintenance people changing some burned out leds.
Some interesting stuff I learned from http://videosystems.com/ar/video_new_dimensions/ :
One Reality Check project involves a corporate installation in Times Square in New York City. It’s a huge, animated sign on the side of the Lehman Brothers building. The sign shows a mix of animation, information, messages, and mood based on changes in market news, the weather, time of day, or Lehman’s discretion.
The sign is a huge system of LEDs, 5340Ã—736, that stretches vertically from the third floor to the fifth floor of the building. Horizontally, the sign wraps around the building from halfway down the 49th Street side across the entire length of building facing Times Square, then halfway down the 50th Street side. Uniquely, the building’s windows are not obscured by the sign. Rather, the sign is built around them.
By incorporating the sign into the building’s facade, the architects, Kohn Pedersen Fox Associates, followed the letter and the spirit of a new city ordinance pushed by then-Mayor Rudolph Giuliani. That ordinance required any new construction in Times Square to have electronically lit signage with a size compensatory to the size of the building. While on many buildings those signs are little more than placards jutting off a facade â€” a giant Coke bottle or lit billboard â€” the Lehman Brothers building is itself an electronic sign.
Of course, the odd shape of three large horizontal bands connected by narrow vertical bands of LEDs between the windows of the building begs non-standard content. There are no 4:3 video images here to captivate the tourists.
The sign is kind of cool. I sometimes go to the Starbucks across the street to sit there and watch it.
