I discovered QR Code :)

"A QR Code is a matrix code (or two-dimensional bar code) created by Japanese corporation Denso-Wave in 1994. The "QR" is derived from "Quick Response", as the creator intended the code to allow its contents to be decoded at high speed. QR Codes are common in Japan where they are currently the most popular type of two dimensional code." - source article at Wikipedia

I know this stuff has been around for years. I just got my first camera phone, so its all new for me :happy:
check out some of the codes i created. in case you still don't know, you need to use special software loaded on yr camera phone to read the codes (scroll down to a link to the free software)
