P.S. My optical cortex is undoubtedly loony. As an opthamologist remarked, if you think they're real you need another kind of doctor! I haven't been able to see the E on eye charts for three years: some optical hallucination covers it. If I could draw the faces I see I could make a fortune designing monsters for movies. At first they were quite varied, both realistic and fantastic, but they've become a bore in silly shades of green.
