Abstract: A moving platform system with a base firmly anchored to a supporting surface and an upright structural member extending therefrom. A bifurcated arms assembly is mounted to the distal end of the structural member supporting a cross bar assembly. The bifurcated arms assembly includes two outwardly extending arms that support two of the four legs of the cross bar assembly. The other two legs support the platform that in turn supports the object being displayed or used as an entertainment structure. An electric motor is used to provide rotational movement to two wheels of different diameters. The wheels are pivotally connected to linkage arms at an offcentered position that provide the reciprocating sinusoidal movement to the platform with different frequency characteristics.
