I'm not much of a football fan, but when the 50th Super Bowl came around, I thought it would be cool to have the scores displayed on a RGB LED matrix. The data is read from the NFL's data base, using a simple API, which the game status is updated in real time. A Raspberry Pi B+2 both drives the display and retrieves the data from the server. Got it done just in time for the game.
The NFL does provide nearly every single pice of data you would want from a game via their API.
