Blinky Lights and Rumbling Wrist Rests Stephen Fung January 18, 2007 Philips was showing off this little piece of sunshine at CES… The Philips AMBX sound system for the computer world will be available this March. It features a rumble bar which is meant to be located in front of the keyboard as a wrist rest. The bar will vibrate with games and music and the satellites speakers will glow and change to different colors with the sound. You could have your own little disco party at your desk.
