How to make a network status display?

I have seen these in the offices of a few IT departments, and they are really cool and I have decided I need one of my own.

What I want to do is mount a flat screen on the wall and connect that to a computer. I then want that computer to cycle through the various web interfaces from our network products to give an overall display of our network status.

Does anyone know of an application that could achieve something like this?

Thank you!
