Hackaday has an article about a 3D advertising sign in Times Square.
Coca-Cola has updated their sign in Times Square, and this one has a mesmerizing 3D aspect to it, giving the spooky feeling you get from watching buildings curl up into the sky in the movie, Inception. That 3D is created by breaking the sign up into a 68’x42′ matrix of 1760 LED screens that can be independently extended out toward the viewer and retracted again. Of course, we went hunting for implementation details
The article looks at the available information on the display modules, and the control of the sign. It also has links to video of the sign in action from the designers, Radius displays

Reading the hackaday article, it seems they have patented putting LEDs on the fronts of filing cabinet drawers (effectively). Of course there are a number of improvements, the drawers move in and out under program control...and they have at least tried to make the whole thing weather proof (an ice storm might be a problem?)
In the comments, someone claims to know that it was all programmed in Delphi (Pascal).
