Hi, Mack. I am currently developing a radar system to use in my airport's control tower. It has a 100-pixelbrick display and illuminates a single pixel to show the location of an airplane (or other vehicle). You can set the color which each vehicle appears in the display. For instance, I am making all Passenger Jets appear green, all Private Jets appear orange, and all small planes appear blue. If you are interested, I would be more than happy to give you the mod and help you set it up in your control tower. I will post a video of it here after I get home in about 1.5 to 2 hours.
EDIT: The video is currently being converted on Vimeo and will be done in about 35 minutes. I will post back here then.
