The mobile has twelve elongated members positioned with respect to one another to create the appearance of a hexahedron. At each of the eight corners is a flexible joint means joining three rods together and permitting the rods to pivot relative to one another (but maintaining their attachment) so that exterior forces such as air currents or mechanical thrusts cause the mobile to move in an undulating fashion and thereby create changing hexahedron shapes or patterns. The mobile is suspended from a ceiling or from an arm on a stand. Suspension is attained by a pair of threads which are respectively attached to an opposite pair of top members.
