Our very own desi version of the flea market, the colourful Ravivari or Sunday market on the banks of Sabarmati at Ahmedabad is a rustic attraction since time immemorial. The cacophony of vendors trying to sell their wares, the lavish spread of cheap, second hand goods and the riot of bright plastics and junky metal, is a typical weekend spectacle. A visual display of perfect order in chaos, a walk through this unique bazaar is an engaging experience and an informal lesson in understanding various elements and principles of design in action
