The Ripple Interactive LED Coffee Table is one of the coolest ideas I've come across. It contains 480 super-bright white LEDs and optical sensors to provide illuminating feedback when objects are placed near the surface. I can see it perfectly at home in a trendy bar or lounge. The lights would be a trippy effect. It's priced rather high at $1,500 to $2,100 depending on length though. There's no doubt that I'd love to own one.
