Biennale: QR Code Cathedral

Who said QR Codes are dead? At least in Russia they don’t think so as you should if you build a cathedral out of them?

At the thirteenth International Architecture Exhibition during the Venice Biennale. they present a Dome build out of QR-Codes. Each QR-Code links to a picture and lights up periodically. All visitors are given Tablet PCs that help to decipher the codes and see the images.

QR Code Embedded Images

QR Code with embeded image

QArt Coder is an online tool that allows to embed images into QR Codes.

QR codes are 2-dimensional bar codes that encode arbitrary text strings. A common use of QR codes is to encode URLs so that people can scan a QR code (for example, on an advertising poster, building roof, volleyball bikini, belt buckle, or airplane banner) to load a web site on a cell phone instead of having to “type” in a URL.

QR codes are encoded using Reed-Solomon error-correcting codes, so that a QR scanner does not have to see every pixel correctly in order to decode the content. The error correction makes it possible to introduce a few errors (fewer than the maximum that the algorithm can fix) in order to make an image. QArt Coder exploits that to embed an image into the QR code.
