Nicolas,
I do not mind other folks choice of a non-orthogonal projection of their angle of of view! I only care about such personal choices when it would mean yet others are unfairly limited in some really significant way. That is not the case here. There was an idea in Fahim's head and what he did is put it, as best he could into this form. He is allowing us to essentially enjoy it or not as we see fit!
I would defend almost any choice of viewing angle as a basic principle. I myself might want to crowch down or even lay flat on the ground. So I almost never object to odd angles in artistic expression and although I might not agree with that as the best choice, I will strive to harvest the fruit of the offering as given.
I imagine that Fahim looked up and was impressed that one didn't need to capture all of of the room as designed by the architect and fitted out by the decorator. Rather this slice, was itself impressive and interesting. Nothing more was thought to be needed, not even orthogonality! Sorry for that!
Fahim Mohammed: "Simplicity"
"In life, as in photography."
We have the intelligence to add the rest, (if we feel such a need), but it could be that Fahim wishes it to be viewed as "complete in itself"! Well there is the paradox of art! If it were
utterly complete then we would have no choices to make and nothing to bring to it.
Whenever there's ambiguity, we are invited to solve a puzzle.
But the surprising and perfectly defendable answer to the proposition of an apparent "puzzle" might be that there is no puzzle at all and absolutely nothing missing!
It could be very much like the case of Magritte's picture of a pipe, not a pipe and not ever intended to become one!
