For Code your mind, we created large format QR billboards for smartphones. The idea was to extend QR code visibility and legibility to an urban environment. A legal solution - use the "free expression" billboards dotted around the city. The principle - put up a QR code associated with a message; after flashing the code, the reader is met with a video. Its content advocates QR codes, or more precisely the digital age. The video reveals a society (image of man) becoming more and more dependent on technology, and the transformation of human thought into digital. The human being is packaged in a pattern of thought which he himself created, without any possibility of escape.
