• Spilhaus Clock (Spilhaus Space Clock), built by Edmund Scientific, shows the position of the stars, tides, phases of the moon, and position of the sun and moon. The clock has a series of seven transparent discs, each turning at a different rate and showing different information. There is a full reproduction of the manual for the clock, helping with the complex process of setting the time and other indicators.
  I also provide repair parts and restoration services for this clock.
• Lunarium shows the moon relationships, position of the sun and earth.
• Geochron, shows the sun lit portion and time on a scrolling map of the earth
