Their website has a bit of information for the public including some lively forums, but the real treasure trove is MagicPedia. There, you can find over three thousand biographies, information on almost 1,700 books of and about magic, nearly 200 magic organizations, and so much more. The current featured article is on the American Civil War, and the role numerous magicians played at that time.

Various Optical Illusions

"I am fascinated with the science of optical illusions. What happens in our brain when we view an optical illusion? The information gathered by the eye is processed in the brain to create an idea or image that does not match with a physical measurement of the stimulus source. On this channel you will find a variety of videos that will spark that scientific corner of your brain." [more inside]

THAT'S A BONE

Few phenomena have the power to confound as many different types of people as pareidolia. It doesn't discriminate by culture or religion. It causes Christians to see Jesus and Mary, Muslims to see the names of Allah and the Prophet, Jews to see the Star of David, Hindus to see the monkey-god Hanuman, and Buddhists to see — you guessed it — the Buddha. Even atheists who haven't devoted themselves to skepticism have puzzled long and hard over the famous face, and more recently, Bigfoot, on Mars. Now video has surfaced on YouTube of pseudoscientist and perennial attention-seeker Richard Heene (yes, Balloon Boy's dad) seeing things on the red planet too. If you'd prefer the filler edited out, the remix is highly entertaining. [more inside]

Ernest Becker

The real world is simply too terrible to admit; it tells man that he is a small, trembling animal who will decay and die." “The defenses that form a person’s character support a grand illusion, and when we grasp this we can understand the full drivenness of man. He is driven away from himself, from self-knowledge, self-reflection. He is driven toward things that support the lie of his character.” Words of Ernest Becker, here summarizing Gestalt therapy and his own existential perspectives in Growing Up Rugged.

Art of Deception

The sculptures of Shigeo Fukuda show that shadows and reflections (mpegs) may not be what they appear to be. When you turn M.C. Escher's drawings into sculptures, you can get some impossible objects (mpeg). And Dick Termes paintings on globes are stunning examples (Quicktime) of six point perspective. All of these works of illusionary art are featured in the book Masters of Deception: Escher, Dalí & the Artists of Optical Illusion and must be seen to be believed.

A professor of vision science at MIT understands that life isn't just black and white, even though we often see it that way. This amazing illusion proves it, and these slick, fast-loading, Flash demonstrations of lightness perception show how it's done. (My favorite is the "Koffka Ring".) White paper here, for deeper background.

I'm usually not a big fan of optical illusions (unless there's a nice magic trick built around it), but this one is pretty brain-burning. (Yes, that's my entire front-page post. But hey: at least it ain't a news story.)
