SOS Floor Plan and Configuration Variations

The standard Science On a Sphere set up includes 4 projectors in a square around a 68" carbon fiber sphere. For sites that don't have enough space for the standard configuration, there are many options available:

  • Use projectors with short throw lenses
  • Use a smaller sphere (60" or 48" available)
  • Use fewer projectors

Configuration Variations

If you don't have room for four projectors, then user fewer projectors is a great options. The projectors remain 90 degrees apart from one another and one or two quadrants of the sphere are dark, depending on how many projectors are used. Some sites have opted to put the sphere in a corner or against a wall to help hide the dark areas, as seen below. In each of the floor
