Very small art

Dan Thompson of RAG has pointed me to Worthing's Big Art application, but also points out that at the Start show in Brighton (from 17 November) you'll see some really small art - they recently opened a professional, contemporary gallery in a converted doll's house. All the art is original, just 1/12th the normal size and price. Business rates are more affordable, too. Why doesn't Brighton have something like RAG??
