I spend yesterday wandering around London and, as is my wont, spotted some QR codes which I think may interest readers of this blog. Tracey Emin The Hayward Gallery are having a Tracey Emin retrospective. At the start of the exhibition is this rather odd QR code. Why odd? Three main reasons. It leads directly to a 14MB MP3 file. The code is really quite small considering it's a low-lit gallery. Rather that being printed directly onto the wall, it appears to be a separate…
