It's our early Christmas present to you and it's better than a pair of socks, it's a bra. Seven bras, in fact. The La Senza Cup Size Choir is made up of seven models, each with a different cup size from A to G. Taking it in turns to sing the note that matches their measurement, the choir squeaks out a semi-annoying rendition of Deck The Halls, made bearable by the visuals. At the end you get the chance to create your own tune by clicking on the members of the choir, or playing the a - j keys on your keyboard like a church organ. We're still trying to master The History of Photography in Sound by Michael Finnissy (it's over five hours long). To try it yourself, go here.
