Berlin based urban artist Sweza is no stranger to regular 2d-code readers. He first appeared over two years ago with his ingenious use of QR Codes to preserve graffiti. He photographs the graffiti before it is cleaned off by the local authorities, afterwards he returns and places a QR Code in the cleaned area which resolves to an image of the original (see this post). Another of his ideas was the QRadio, an audio-visual paste up marrying QR Codes, music and a ghetto blaster (see this post). Much like Banksy he prefers to fly under the radar but recently was the subject of a short video by German TV station DW-TV (below in English).
