It is shot with 9 film cameras (rolling simultaneously) arranged in a CIRCLE with all of the backs of the cameras "touching" and all of the lenses pointing outward. This "odd-looking camera contraption" was mounted on top of cars, or hung below the belly of airplanes to allow it to freely move through crowds, down streets, or high above interesting locales.
This system provides 9 film images that can be projected fully in a circle (on 9 screens which have their side edges touching) around the upper half of the walls inside of a circular (cylindrical) theater.
The audience remains standing during the show (hand-rails are provided) and viewers can freely turn fully around to view the film image in the complete circle arc.
There are 8 channels of audio (and speakers) that also circle the room so the audio effects can come "from" any area of the image.
