image shown at 20 representing the view seen from a race car
which is traveling on a road that curves to the right as
indicated by arrow 23. In order to enhance the entertainment
effect, the passenger-holding frame 12 is supported on three
hydraulic rams 24, 26, 28 that support three locations 30, 32,
34 spaced about the passenger frame. The rams can tip the
frame, either to
one side or to the front or back, and can also rapidly raise
and lower the frame. Figure 6 illustrates a portion of the
control system which controls movement of the three rams 24 -
28. The motion picture image is created by an image portion
72 of a film 22 that is contained in the projector. The film
includes a sound track 76 along one edge and a motion control
track 78 along the opposite edge. Three sensors 80, 82, and
84 respectively sense opposite edges of the track and the
density along the center of the track, and deliver
corresponding signals to a control circuit 86. Each of the
sensors 80 - 84 detects signals representing the
position of a different one of the three rams 24 - 28. The
control circuit 86 delivers signals corresponding to those
detected by the sensors 80 - 84 to three valves 90, 92, 94
