For those that want to add some sort of ambient lighting to their PC games might be interested in these amBX devices from Mad Catz.

These devices actually follow the colors on the screen, and change appropriately in order to “set the mood” depending on what game you’re playing.

As my Source says, I have no idea if there is a market for something like this, and I also have no idea how something like this can work.

From what I can tell, the amBX lights should hit the market sometime this year, but I’m not certain when.
