@mark noble,

Hi Mark ! long time indeed...

It is true that a 2 dimensional representation of a Pyramid contains a 2 dimensional pyramid in which the 3 dimension is illusory...nevertheless is a perceptual Pyramid in the representation, what is there after all...

I am not even sure on what dimensions are "true" dimensions instead of programmed coordinates of space in a computational string...for all that I know the Universe might well be made of binary code...
