Visual Trickery !

An article from a magazine I picked up in the eye clinic. 'Plastic Fantastic is how some scientists describe the brain, not literally of course, but in the same way that plastic bends and adapts to new moulds, so too can the brain remould as we learn. Often as vision fades, the brain can fill in the missing pieces with memories.' It was all rather complicated but I loved the brightly coloured pattern.
