I don't really know much about the method :) Got it from a friend, they had a paper accepted to SIGGRAPH Asia this year (Halftone QR Codes, Hung-Kuo Chu, Chia-Sheng Chang, Ruen-Rone Lee, Niloy J. Mitra, SIGGRAPH Asia 2013)
I didn't even know that QR codes are so flexible... My guess is that the paper will be up soon, so we'll see then :)
