Microsoft has recently announced the development of a system to encode more information onto their DVD discs and games by using a “system of colored, triangular barcodes”:http://news.bbc.co.uk/2/hi/technology/6570871.stm. These are not meant to replace the black and white, linear barcodes that everyone knows and loves. Instead, disc owners can use a camera phone to read the data stored in the code and access online materials, extra downloads, or other game-related features.
