the necker cube is triply ambiguous already... it could be a shape 
in, a shape out or, and this is presumably how most eyes in the world 
see it, a few lines on a page..

in fact most (all?) ambiguous figures have this third interpretation 
(which is of course the only 'correct' one) which is so obvious it 
tends to be overlooked...
