    Thanks, Alex,

    I hope people will continue to look for more information. The crux of my argument, which I don't think has been addressed yet, was in the last paragraph:

    "Set a prism between you and a line on the wall. Put the prism near the wall and look at the line from across the room. You'll see the line not far from its true position. Bring the prism close to your eye and you'll see the line a considerable distance out of place."
