smithsax, don't you think it's revealing that the preamble starts with a description of the corners? We can start with the corners because we can say with absolute cerainty what they look like as far as the specific object is concerned. We know that a 90% twist would give us the wrong orientation, so we must actually start by getting the corners right.
Next we move to 'the other letters within the world...' again a connection from the one to the other. There's a gimmick attached to 'the other letters' linking them directly to the quote, but why should this negate how the corners must appear?
I know what the corners of the object look like - anyone involved in this activity knows, because it's only when you've got the corners right that you can begin. The 30 cell shading looks nothing like the thing at the centre of the quote (and what appears in the grid).
