It's a wintery Saturday night in Hollywood, and I am having one of those quintessential L.A. outings. Sitting in the dank, stonewalled basement of the landmark Magic Castle, I am watching psychokinetecist David Gamliel move objects with his mind. Our well-dressed group stares at the short, intense, balding, goateed Israeli as his hands hover over a pair of eyeglasses that sit on a green felt table. His hands begin to make slow circles in the air, and soon the glasses levitate and circle, mimicking his hands' movements. There is an audible sigh. He never touched the glasses -- we all watched.
