The amBX system features lights atop each of four surround-sound
speakers that will recreate the lighting conditions in the game your
playing. They'll dim as your game character enters a dark corridor or
if he gets caught in a flashlight beam from the left, the lights to the
left of you will light up. The system also includes four miniature fans
to replicate gusty winds to go with those rumblings of thunder.
Sound interesting. What do you think?
