>and at those sizes angular size is essentially linear even when projected onto a flat screen. But not quite, and summed over many pixels, it will result in a noticeable discrepancy (which is still of no practical consequence). I wonder how it would feel to use a computer that used head tracking to dynamically transform the screen's contents so that pixels were mapped to equal angular size (from the point between the user's eyes).
