ABSTRACT:
There now has been discovered a simple, straight-forward apparatus for animating figures through the use of the apparatus and method of the present invention. The apparatus and method employ a plurality of collapsible, fluid chambers, and associated values controlling the fluid pressure in each of the chambers. At least two of the chambers are physically arranged so that the inflation of one such chamber and deflation of the other complimentary chamber causes all or a part of the figure to assume a different spatial position, dependent upon the level of inflation of each of the chambers. Typically, at least two of the chambers are arranged so that the inflation of one such chamber exerts a physical force on the other.
