Dioramas are very popular. A few companies created little "scenes" depicting the good safe American life. At Uttrak, a plastic old man sits on a park bench enjoying the day with a Buster Brown boy in a little baseball hat and mitt. A little dog is arfing at their feet. Cameras are trained on the scene, recording every move the tiny figures could make on several monitors—the figures, however, are immobile.

Thankfully, the company whose CCTV system was flogging its ability to create hypersensitive motion detection zones—say, near a safe or the office water cooler—opted for a full-motion diorama. Again and again, a little doll businessman enters a little doll office with little doll folders piled high on a little doll desk. Each time the doll nears the desk the camera clicks on to record his suspiciously monotonous activity.

CSI, who specialize in home security, have a life-sized diorama set up. "Welcome to the High Tech Habitat," a sign over the airport metal detector door reads. Inside a stereo is playing and within every Bed Bath and Beyond-ish picture frame, every "L.A. Law"-like desk clock, every cutesy clown portrait, and even one smoke alarm, a camera is hidden. It all vaguely resembles the "home of the future" diorama you see in line at Space Mountain, save the flies and barfy Disney ketchup smell.
