E-Shirt of the Day: With the help of an Arduino Lilypad microcontroller, a bunch of LEDs, some conductive thread, and a Bluetooth dongle, Chris Ball and his wife Madeline whipped up a TSA-baiting electronic T-shirt capable of displaying the number of unread e-mails currently awaiting their attention.

Check out the video above to see the shirt in action.
