Display Computer: PC minimum P4 processor 2.0 Ghz and 512Mb, running Windows 2000 or XP. Sound card required. Projector: Minimum 1500 ANSI Lumens, XGA, short throw will be needed in most spaces (ceiling heights 10'- 15'). Currently using Canon LV-7215. Camera: Any color surveillance camera with AES (auto-exposure) and more than 320 lines.

Table: 8 foot diameter made out of wood, 8 inches depth for sand, 18 inches off the ground (speakers go under). Mirror: For the projector. Size depends on the height of the ceiling. It can be a good quality plexiglass which is not as heavy as glass. Sand: White

A reflecting mirror (in order to make total distance from the projector larger) should be installed on the ceiling. The mirror is about 25" square, mounted at a calculated 55 degree angle, and is first-surface mirror like in AM Table above. The projector is mounted from the ceiling using a custom-built adjustable hanging mount. This installation uses a large AVI movie file that has to be transferred to an external PC drive. Software setup involves proper circular masking (to the edge of the table) of the projection. The movie file is at 1024 X 768 resolution, and the projector resolution should also be the same. You can start the Director application and move the image up, down and sideways using the arrow keys. The image can be made larger or smaller by zooming the projector, throw ratios allowing. Make sure to remove the keyboard after adjustments are made, and also check that the mouse cursor is not in the viewable area.
