By timing the images on the scope, you could place them at a particular depth. The mirror was excited by a regular ole' loudspeaker at 30 hz (maybe it was 60); it was counterweighted so that its vibration was parabolic rather than spherical. Eventually, Genisco bought the technology and reengineered the package to sell as their own. I don't believe they have had much luck selling it. I thought the images it produced were quite striking. I could chase down references if anyone's interested. /jr Brought to you by Super Global Mega Corp .com
