This is a video board created for DuClaw Brewing Company to display what's on tap at the Maryland Brewer's Oktoberfest. Created to run on Xbox 360 or Windows 7 connected to a big ass Flat Panel television and a set of very loud speakers. The board also plays promotional videos on a set schedule and has a few more animations and effects not shown in this clip. The board actually runs on 3 different screens all with their own content, beer selection, videos, etc. We wrote the original for Oktoberfest 2009 and it gets updated each year. It's pretty much a giant video game written with XNA and C#.
The information that follows pertains to an older version of XNA and may not be applicable Imagine an XNA game running two monitors, one for the 3d game, and a second having a full screen tactical map of the game. The easy part is actually splitting the game windows to multiple monitors, the difficult part is synchronizing the two parts to work together (which I will leave up to you). You can create a simple subclass of GraphicsDeviceManager and then create the two game windows on separate threads. When instantiating the Game class, pass in the index of the monitor you want to target (the index is visible in the display options dialog of your pc).
