Frank Zhao's USB PCB Business Card tutorial from Instructables. Check out the video below as well.
This is a business card that will type out some text when you plug it into a USB port.
It uses a ATtiny85 microcontroller with V-USB based code to emulate a keyboard. The typing is triggered by the CAPS LOCK status LEDs being toggled 3 times.
This instructable will focus on using CadSoft EAGLE to create your own USB PCB business card. I want you to be creative in the design, so some minor steps I've taken may have been omitted....
