As I finished up the final touches to the skullcap, I had to stand back and take it in. Hooked up to one of the world’s fastest computers, the cap was supposed to be able to scan the brain for any possible problems that could arise. I had gotten the idea from watching a late night movie called “Brainstorm.” In the film, Christopher Walken and others created a device that could read a person’s memories and play them back into another person’s mind.
