Abstract: A motion simulator in the form of a motorized skeletal sphere suspended from a gimbal platform. The skeletal sphere comprises two orbital tracks, each having contollable motorized ballasts devices with attachment mechanism to the orbital tracks. These tracks provide a predetermined path for the ballasts to travel on. The ballasts provide a shifting mechanism for controlling the center of gravitys' position from within the occupied sphere. The ballasts rotate the sphere on its' axis 360.degree., in a controlled and deliberate manner. Different positions of the rotating axis are provided by the use of a multi-pivotal platform, that suspends the sphere and allows it to rotate freely in a plurality of directions. Direction is determined by an occupant using a control device for the ballasts movement. An adjustable chair is provided for centering the occupant as close to the center of the sphere as is possible.
