72 Optical Illusions and Visual Phenomena
[Sept] 14, 2007
Commentary by Stephen Downes

Another optical illusions page. I've been working through the examples over the last few days. What I really like about this site is than not only does it present the now familiar illusions, but that it also provides explanations for the phenomena and links to the scientific papers describing them. My favorite is this illusion - not so much the effect created by the occluders by rather the effect created by looking elsewhere on the page. Via Peter MacKay. Total: 99
