A somewhat flexible floor assembly is supported by a matrix of spaced-apart vertically-adjustable devices, such as electrically-operated jacks operated by servo motors. The devices are centrally individually controlled whereby height of the devices may be individually varied so that the floor surface may have its contour varied as desired. Somewhat flexible metal rods are supported by the jacks, and they in turn support joist assemblies which support a subfloor and flooring surface. The vertically-adjustable devices may be controlled by a computer, which may access data corresponding to a number of selectable pre-configured contours, such that selection of one of the pre-configured contours causes the height of the devices to vary so as to move the floor surface to a configuration corresponding to the selected pre-configured contour. The pre-configured contour may be, for example, a simulation of a real-life golf green.
