Debian developer and Internet Mail Archive founder Jeff Breidenbach of PARC has made GlyphChess, a chess-playing scanner using Python, Gnuchess, SANE, and DataGlyphs attached to the bottom of the pieces.
DataGlyphs are cool 2D barcodes made out of / and \ marks for 1s and zeros that use the Reed-Solomon coding from CDs for error coding.
