While browsing t'interweb (using the magic of Stumble Upon), I came across a website where you can create your own barcode using pieces of personal information. This is mine:
Each barcode is also given a value - from memory mine was $6.24. You can create yours here.
The site is worth having browse around - especially for the supercool barcode clock although the Braille and Sign Language clocks are also cool!
Enjoy!
