There's a multitude of art in London, from the finest masterpieces from the Old Masters to modern conceptual schoolboy rubbish. Keeping track of all that is on (TimeOut listings stretch to 25-30 pages at any one time) is quite a challenge, and after missing the umpteenth exhibition that I had desired to see, the outcome was this page. It's far from perfect, constrained by Google Apps simple list style. It does, however, do the job.        - Sam Crawley
