Now that that's over with, it is probably worth saying that this the piece is aesthetically pleasing, but it's more design than art. Batchelor admitted openly that he came up with the idea quickly on the back of a piece of paper, and when it was chosen he commissioned someone else to put it together. On Tuesday night, he seemed much more interested in flogging his book than discussing any vision behind the work, and perhaps that's ultimately because it's quite a simple work based around a simple pattern. Nevertheless, it's quite pleasant, working well with the light coming through the roof, and Batchelor seems at ease with what he's doing, which is putting up 20m x 10m of stained-glass-style coloured perspex shards above a platform in a famous train shed.
