Abstract: An entertainment device is based on a sphere that moves in coordination with visual and auditory stimuli. Audience members are seated inside the sphere in one hemisphere while an image is displayed on the inside of the opposite hemisphere. The sphere is driven by actuators to roll, pitch and yaw without limit in synchrony with the images displayed. An audio system works in synchrony with the motion to further enhance the experience. Pure horizontal or vertical motion effects may be obtained by adding one or more linear motion stages which translate the entire sphere assembly horizontally or vertically. The audience members may interact with the ride using actuators. Multiple spheres may interact with each other.
