A research team led by Susumu Tachi from the University of Tokyo has developed a rotating panoramic display that immerses viewers in a 3D video environment. The Telexistence Wide-angle Immersive STEReoscope, or TWISTER, is the world’s first full-color 360-degree 3D display that does not require viewers to wear special glasses, says professor Tachi, who has spent over 10 years researching and developing the device.

Inside the 1.2 meter (4 ft) tall, 2 meter (6.5 ft) wide cylindrical display are 50,000 LEDs arranged in columns. As the display rotates around the observer’s head at a speed of 1.6 revolutions per second, these specially arranged LED columns show a slightly different image to each of the observer’s eyes, thus creating the illusion of a 3D image. In other words, TWISTER tricks the eye by exploiting what is known as “binocular parallax” — the apparent difference in position of an object as seen separately by the left eye and the right eye.

So who killed the record industry as we knew it? "The record companies have created this situation themselves," says Simon Wright, CEO of Virgin Entertainment Group, which operates Virgin Megastores. While there are factors outside of the labels' control -- from the rise of the Internet to the popularity of video games and DVDs -- many in the industry see the last seven years as a series of botched opportunities. And among the biggest, they say, was the labels' failure to address online piracy at the beginning by making peace with the first file-sharing service, Napster. "They left billions and billions of dollars on the table by suing Napster -- that was the moment that the labels killed themselves," says Jeff Kwatinetz, CEO of management company the Firm. "The record business had an unbelievable opportunity there. They were all using the same service. It was as if everybody was listening to the same radio station. Then Napster shut down, and all those 30 or 40 million people went to other [file-sharing services]."

It all could have been different: Seven years ago, the music industry's top executives gathered for secret talks with Napster CEO Hank Barry. At a July 15th, 2000, meeting, the execs -- including the CEO of Universal's parent company, Edgar Bronfman Jr.; Sony Corp. head Nobuyuki Idei; and Bertelsmann chief Thomas Middelhof -- sat in a hotel in Sun Valley, Idaho, with Barry and told him that they wanted to strike licensing deals with Napster. "Mr. Idei started the meeting," recalls Barry, now a director in the law firm Howard Rice. "He was talking about how Napster was something the customers wanted."

The Dunning-Kruger effect is the phenomenon whereby people who have little knowledge systematically think that they know more than others who have much more knowledge.

The phenomenon was demonstrated in a series of experiments performed by Justin Kruger and David Dunning, then both of Cornell University. Their results were published in the Journal of Personality and Social Psychology in December 1999.

Kruger and Dunning noted a number of previous studies which tend to suggest that in skills as diverse as reading comprehension, operating a motor vehicle, and playing chess or tennis, that "ignorance more frequently begets confidence than does knowledge" (as Charles Darwin put it). They hypothesized that with a typical skill which humans may possess in greater or lesser degree,

1. incompetent individuals tend to overestimate their own level of skill,
2. incompetent individuals fail to recognize genuine skill in others,
3. incompetent individuals fail to recognize the extremity of their inadequacy,
4. if they can be trained to substantially improve their own skill level, these individuals can recognize and acknowledge their own previous lack
