For some people, getting an email or text or tweet is cause for a mini celebration. But how does one celebrate such small samples of communication? With light, of course! Duh. Sheesh. The L8 SmartLight ($69) is made up of 64 RGB LEDs on one side and a single super RGB LED on the other. Hook it up to your phone via Bluetooth or your PC and you’ll be getting dazzling or dainty displays of light whenever you get a Facebook friend request or a 2:47 long voicemail from mom. Those are the best, aren’t they?
