Claim:
A self-centering mobile, comprising: a frame; a plurality of freely rotatable connectors; a horizontally disposed arm having two ends and a balance point between the two ends, the arm suspended from the frame at the balance point with one of the freely rotatable connectors; and a display member suspended from each end of the arm with another one of the freely rotatable connectors and having a weight so that the arm is balanced when suspended from the frame at the arm balance point, wherein the freely rotatable connectors comprise a spinner assembly adapted to rotate freely for 360 degrees in both clockwise and counter-clockwise directions and a means for attaching the spinner assembly to the frame and to the arm, and wherein the means for attaching the spinner assembly to the frame and to the arm comprises a dual lock snap fastener comprising a round rod of spring steel formed into an elongated oval-shaped body, the rod terminating with a first end and an overlapping second end on a first side of the body, wherein the second end is bent approximately perpendicularly to a longitudinal axis of the fastener across the fastener body and releasably around a second side of the body opposite the first side to form a first lock biased by the spring steel, and wherein the first end is bent approximately perpendicularly to the longitudinal axis of the fastener away from the fastener body and releasably around the first side to form a second lock biased by the spring steel.
