I have always had a fascination with optical illusions. I suppose it's the deliciousness of having my eyes and brain being deceived in such a way. I'vecollected made for children that contain them as well as works by the likes of Professor Richard Langton Gregory, a psychologist who wrote about how and why we preceive things as we do. Later on, this Optical Illusions section of the website was one of the first I wrote and later still, I wrote a short paper on the subject for my college psychology class.
Thanks to an email from Peter Shearn, a fellow Bristolian, who reminded me of the cafe at the bottom St Michael's Hill.
Thanks too to Patty Waltermire, Mark Griffiths and John Mitchelmore who sent me more material for these pages.
