What pattern (if any) do the flashing lights on the back of an ASUS G50 laptop follow?

The are supposed to flash along with games that you play, I guess.
“The G50 is the ultimate gaming rig. Equipped with a 16:10 15.4” display, pulsing LEDs that react to gameplay…” is a quote from a Microsoft page. So they may pulse to sound? Making music the most likely reason, or maybe any sound in general. In terms of programming them? Not heard of it.

Ok, thanks. I will definately watch what happens when I play something with big booms.
