Abstract: A manually operated motion device for user interactive motion of a motion surface. The motion device includes a motion surface with a support points in a substantially triangular arrangement and that are used to support the motion platform in a substantially parallel relationship to the floor by a pair of support members attached to universal hinges on the motion surface and a compression member which connects to a universal hinge on the motion surface and may move in a substantially vertical plane that bisects the triangular arrangement of the support points on the motion surface. Attached to the supports is at least one mechanism for manually moving at least one of the support members, so that motion of one support member allows motion of the motion surface.
