This is my rendition of the globe from Storyboard II. I imagine retrofitting an existing victorian-style globe to develop this prop.
The globe is wrapped inside a metal frame which contains a visible marker to identify clues. The frame will rotate about a vertical axis using a motor and gear train that is fitted inside the base (lower left). This mechanism could also be placed inside the table that the globe rests upon. This frame would be manufactured from brass (or painted to look like it) because the antique look would better fit the setting.
The globe is rotated about a tilted axis by another motor which is embedded in the holder. This motor needs to be small. Therefore, in order to produce the desired rotation, I have implemented a compact planetary gear set much like the one found in small hand-held drills (lower right). The "whirring" sound of this motor will also provide some audible feedback to the patrons.
