Description:

• The exhibit consists of an acrylic globe mounted in a Plexiglas case on a laminated tabletop.
• The rear of the table is supported by a laminated pedestal concealing the power cord to the floor.
• The front of the table is supported by two Zero truss legs and floor pedestals.

Visitor Activity:

• A clear acrylic sphere with the outlines of the continents illuminated by a bright point-source light from inside.
• The image of the continental outline is projected onto a flat screen which is viewed by the visitor.
• By pushing a button, the visitor can move the light from the center of the sphere to the far edge of the sphere.
• When the button is pushed again, it moves back to the center (i.e. pushbutton initiates the movement and is inoperative until the movement is complete).
• The two positions of the light correspond to two different types of map projection. The lamp illumination is controlled by a second momentary pushbutton (i.e. the lamp is “on” only when the button is depressed).

Condition:

The unit is used, but in great overall condition.
