The Cave: Virtual Future Of Planning?

Step into it, scientists say, and you will step inside a three-dimensional image -- a city street, perhaps, or a space station flying over Earth, or even a throbbing human heart. Other machines have promised similar experiences. What makes this one so convincing is that you always see the image from your perspective. Turn your head to the right, and the image is instantly redrawn -- just as in real life. You can move through the virtual world, walking or flying, if you wish. You might even meet someone there.
