--This demon watches the sky. It streams information out of the sky and to the astronomy computer below.
Astronomical observations are all about time, so the clock in the front tracks the orbits of three planets. When the star chart on the base is turned, the solar system turns, and turns the four astronomical objects at top. A planet model on the back corner (not visible) also turns. The entire structure is supported by planets representing the elementals- earth, water, fire and air.
