    'IN 1816. DAVID Brewster. a Scottish mathematician and physicist, invented a new kind of optical device. A narrow tube. fragments of coloured glass gathered loosely at oen end were rearranged as the tube turned, refracting a series of recombining mandalas  for the viewer (at the other end) thanks to mirrors set inside. A slight turn and a whole new vista appeared - impossible to predict, to enumerate. to return to. Brewster called it a kaleidoscope, a 'philosophical Instrument* that changes what was possible to 'see' and how.' (Ashley Hey : Introduction)
