We came across Frank's innovation in making his own Business card using a ATtiny85 microcontroller running the AVR bit-bang V-USB stack.

When the Caps lock key is pressed thrice then this card prints out the complete contact information on Notepad. This device basically emulates a USB keyboard using the HID profile and senses the key presses on the system. Then after the valid key presses it starts to generate a stream of key presses to type in the information.
Impressive portray of what a geek can have as a style statement.
Complete Documentation along with schematics and code is available on Frank's Website. Check out his development for AVR based USB HID profile devices call : USnooBie. This is compatible to Arduino and can be directly plugged into the PC. Its also commercially available at Seeed Studio.
