This is a product that is popular for people who like movies or games. it attaches to your chair or goes under the sofa leg and gives the chair some kind of vibration motion based on the sound input. it allows you to really "feel" the action in the video, supposedly.
Anyway, I'd like to see someone try this with a CH video or otherwise.
