How the HelioTrak Sundial Works, a Transparent World Globe

To understand how the HelioTrak sundial works, consider the lines the define the tropics on a world globe. The Sun is directly overhead on the Tropic of Cancer in June, on the Equator in March or September, and on the Tropic of Capricorn in December.
The land area between these lines is the tropics. At any given moment, the Sun is directly overhead somewhere in the tropics. When the sun is shining, you can find that spot by orienting the globe like the Earth. Then the Sun lights up the globe just like the Earth.
The solar tracking cage of the sundial has the same lines as the globe: Equator, Tropic of Cancer, and Tropic of Capricorn. When I tilt the cage to my latitude of San Francisco and orient the axis toward the North, the sundial is in the same orientation as the real Earth.
The flat plate represents my view of the horizon, and the sky above, at my location. The solar tracking shows the Sun's path through the sky. the Sun rises in the east, reaches its highest point at noon, and sets in the west. The solar paths vary over the year, from the Tropic of Capricorn, to the Equator, and to the Tropic of Cancer.
To find out where the sun is now, point to the spot on the cage that casts a shadow on the center of the plate. From there, you can read off the time and date from the solar tracking cage.
