The photographer of mass naked people, Spencer Tunick, will be in Melbourne soon to take photos of naked people on the rooftop carpark of an inner suburban supermarket.
The supermarket, Woolworths, ran a mile from such a thing, but coyly suggested the problem was lack of parking for customers. It subsequently correctly judged public opinion and the photo shoot will go ahead. The space is limited, so expect only hundreds of naked people, not thousands.
Some countries in the world, such as Japan, seem to have much less of a problem with nakedness, of the old and young.
