Local eccentric and self-styled music expert Dr Hapuka makes a meagre living on the side, selling stuff from his home made Whirligig. An elaborate kinetic sculpture constructed on a still rideable bicycle, the Whirligig also doubles as a mobile hawkers office from which Dr Hapuka sings his never ending sales patter, to backing music. But what exactly is it that he has for sale? No one’s actually ever seen him sell anything, but this apparent lack of success doesn’t seem to dampen his enthusiasm.
