Perception puzzles, Visual Perception, Optical illusions and Paradoxes
This page illustrates that our visual perception cannot always be trusted. The components of an object can distort the perception of the complete object. Our mind is the final arbiter of truth. Most optical illusions are the result of 1) incongruent design elements at opposite ends of parallel lines, 2) influence of background patterns on the overall design, 3) adjustment of our perception at the boundaries of areas of high contrast, 4) afterimages resulting from eye movements or from kinetic displays, or 5) inability to interpret the spatial structure of an object from the context provided by the picture.

Founder's Blog - Jitbit: Chinese Magical Hard-Drive This is Founder's blog - Subscribe - About Apr 7 2011 A Russian friend of mine has posted this absolutely amazing story.

A couple of days ago a customer has brought a broken 500Gb USB-drive that he had bought in a Chinese store across the river, for an insanely low price. "Hacktivists" Fight Terrorism From Their Home Offices Article written by guest writer Kecia Lynn What's the Latest Development? Citizen "hacktivists" are working to infiltrate Web sites belonging to terrorist organizations and their supporters, supplying the US military and FBI with data that can be used to help identify individuals and activities. Because this network of individuals isn't "official" or organized, the data supply is "a one-way street," according to Jeff Bardin, a former Air Force linguist who has spent years developing various personas that he uses to penetrate terrorist sites. He became a hacktivist after entering Al Qaeda bulletin boards and seeing videos of attacks on US soldiers.

Fruit (Bowl) Loops: 8 Circular Wood, Glass & Metal Designs Circular forms are a clear choice for storing the rounded forms of fruits – but these creative modern design ideas are anything but obvious. For starters, when someone asks you to pass them this vertical wooden fruit ‘bowl’ just give it a nudge and send it rolling their way – just don’t slip while sliding them the bananas! This nifty set of wood, metal and black-painted plastic half-bowls – also by the artist Helena Schepens – does not have quite the same moves but is still quite dynamic. From tiny grapes to sizable pears and appleas, each piece of fruit added to or subtracted from the mix changes the angle of the centerpiece. To round it out, other designers have developed turn-style systems allowing you to rotate your fruit into place and pop it out of the mix (like the metal one shown on top or the white wall-hanging repositories at the bottom.

How to Get a Copy of Your FBI File (idea) The Freedom of Information Act is a powerful thing. If you've ever wanted to know just what those guvmint bastards have on you, anyway, here's your chance. Just fill in the italics in this form letter with the appropriate information, get your signature notarized, send it off, and you're in business! This should be free, though if your search returns reams of information, you may be charged 5 cents per page in duplication fees. The law says that your request must be responded to within 10 days, but you can expect something closer to 2 or 3 months for a definitive answer with the current backlog of paperwork.

Behaviourism If you want to follow your own links, use "behaviorism" (sic.) Most of the material is US-based and "behaviorism" and "behaviorist" is how they spell it, and I freely admit that this side-bar is purely to get the stupid search engine "bots" to register "behavior" Behavioural (or "behavioral") theory in psychology is a very substantial field: follow the links to the left or right for introductions to some of its more detailed contributions impinging on how people learn in the real world.

30 of the World's Greatest Wedding Cakes Few things are more important on a wedding day (apart from both partners turning up; the ring being secure; and nobody objecting during the ceremony) than the cake. Very few weddings are without such a centrepiece. It's just a shame that so many couples opt for the same traditional, boring designs when there is so much opportunity to impress and surprise the guests.

Finding Vivian Maier: A New Documentary About One of the World’s Most Mysterious Street Photographers In 2007 Chicago 26-year-old real estate agent (and president of the Jefferson Park Historical Society) John Maloof walked into an auction house and placed a $380 bid on a box of 30,000 prints and negatives from an unknown photographer. Realizing the street photographs of 1950s/60s era Chicago and New York were of unusually high quality he purchased another lot of photographer’s work totaling some 100,000 photographic negatives, thousands of prints, 700 rolls of undeveloped color film, home movies, audio tape interviews, and original cameras. Over time it became clear the photos belonged to a Chicago nanny named Vivian Maier who had photographed prolifically for nearly 40 years, but who never shared her work during her lifetime.

Madonna–whore complex In sexual politics the view of women as either Madonnas or whores limits women's sexual expression, offering two mutually exclusive ways to construct a sexual identity.[4] The term is also used popularly, often with subtly different meanings. Causes[edit] Freud argued that the Madonna–whore complex is caused by oedipal castration fears which arise when a man experiences the affection he once felt for his mother with women he now sexually desires. 493 Pokemon Drawn as Sexy Anime Girls Because The Internet, That's Why Okay, everybody, that’s it. We can go ahead and pack it in now, because the Internet has reached its final form. And it happened in the way that I think we all knew it would: With a massive picture of 493 Pokemon drawn as anime girls. At this point, the response is less “why?” than “of course it is.” But I’m not going to lie: As strange and undeniably fetishistic as this is, it’s also kind of awesome, especially the thoroughness of including every single Pokemon to be seen in the games until the newly released Black and White era — including all 28 different versions of Unown, which are of course drawn as sexy maids.
