Oscillatory movements are imparted to plural ornaments of an ornamental assembly from the rotary output drive shafts of a power drive source through a cam assembly driven by each output shaft and connected to plural tappet rods on which the ornaments are supported. Numerous orientations of the tappet rods may be realized to accommodate different positions of the ornaments by detachably securing U-shaped, rectangular-shaped and L-shaped blocks to a casing for rotatably supporting the tappet rods in the different orientations.
