Apparatus and method for providing a dynamic gas-inflated object such as a figure with legs, a torso and head, and a pair of arms. The figure performs generally repetitive movements such as dance-like undulations in a manner that appears to keep time with music. The figure is hollow and connected to a continuous generally constant input flow of air or other gas under pressure. The figure is provided with at least two spaced-apart outlets or vents to allow a continuous discharge of generally all of the air being introduced into the figure. In operation, the figure tends to cycle between extending generally upright, then, as more air is discharged, destabilizing and moving to a contorted or bent position, then, as more air flows in, to extending, etc. The figure may be designed for extensive movement e.g., dancing, or for a narrower range of movements. In a preferred form, the outlets are generally at the top of the head and at the ends of the arms. The dynamic figure movement is a result of the continuous generally constant input gas flow and does not depend upon any intentional intervention.
