The atTiny45 USB LED E-mail, Twitter and Pidgin Notifier

From Just Blair's Audio and Electronic Pages -

Using an Atmel aTiny45 processor, Just Blair has modded his Asus Eee PC 901 with a color-changing LED (red, green, and blue) that notifies him whenever he receive a new message either from Thunderbird (email), Twitter, or Pidgin (IM).

It is a nifty tool but as Just Blair found out all too soon, it can make you a complete slave to email. Whenever the light flashes, you will just HAVE to know what that message is...
