I have probably reported on over a hundred works of QR Code art over the last 6 years but this one has to be in the top three for effort. French artist Jonathan Bréchignac created the unbelievably intricate design below using only blue Bic pens and Ultraviolet ink. His creation titled “Ultraviolet -The Blue Carpet” makes its debut in Brussels, at Villa Empain, from September 27, 2013 to February 9, 2014 as part of the “The Blue Route” exhibition. The work is approximately 2.5 ft × 4 ft, on paper and took eight months to complete. The four QR Codes resolve to four different rather cryptic pages like this one.
