As the saying goes, art happens, just like it did a couple of weeks ago when a piece of art materialized on the dais at the end of Moore Walk. Three globes of varying sizes, which appear to be constructed of wooden pegs and metal rods, hang from a line over the largest sphere. The artist, as yet unidentified, was possibly inspired by the British artist Banksy, who has recently, and surreptitiously, installed his own slightly daft artworks in Paris, London, and New York City museums. Credit, anyone?
