Chris and Madeleine Ball wrote in to share their email-counting t-shirt. Using some parts that they got from the Sparkfun Free Day, they added an LED display to the front of the shirt, that displays a count of the user’s unread email. An Android phone continuously checks the user’s inbox for new messages, then relays the current count over Bluetooth to a Lilypad Arduino on the shirt, which then lights up the correct LEDs. Neat!
