The frame element is dimensioned so as to easily fit upon a desk or countertop. Integral with the frame assembly are two triangular uprights. The first triangular upright 34 has a lower base 36 and an upper apex 38, with the lower base being integral with the first end of the frame element. The first triangular upright further includes a semi circular recess 40 formed within the upper apex of the upright. The second triangular upright 44 has a lower base 46, an upper apex 48, with the lower base being integral with the second end of the frame element. The second triangular upright further includes a semi circular recess 50 formed within the upper apex of the upright. 
     The motor 14 and power transfer means 16 will now be described. The power means includes a motor housing 54 which is integral with the forward portion of the frame element at the first end of the frame element. Positioned within the motor housing is an electric motor 14. The electric motor can be powered by an external source of power through a plug 56, or alternatively can be power by batteries 58 positioned within the motor housing. The electric motor has an output shaft 62 which is coupled to a vertical bevel gear 64. 
     A three way switch 68 is positioned within the motor housing. The three way switch serves to operate the electric motor at any one of three rotational speeds. 
     A timer 70 is set to determine running time for a particular application. Connected with the first triangular upright is a drive shaft housing 74. The drive shaft housing has a lower extent and an upper extent. The upper extent of the drive shaft housing is integral with the upper apex of the upright, and the lower extent of the drive shaft is integral with the lower base of the upright. 
     Mounted within the drive shaft housing is a drive shaft 76. The drive shaft has an upper extent and a lower extent. A lower horizontal bevel gear 78 is mounted upon the drive shaft at its lower extent. The lower bevel gear 78 is intermeshed with the vertical bevel gear 64 of the electric motor. An upper horizontal bevel gear 80 mounted upon the drive shaft at its upper extent. 
     The upper cylindrical housing assembly 18 will now be described. The upper cylindrical housing includes a housing door 84 and a major housing portion 86. The housing door 84 has a first end, a second end, a lower longitudinally extending edge, and an upper longitudinally extending edge. The housing door 84 is defined by a 90 degree hollow cylindrical wedge. The major housing portion has a first end, a second end, a lower longitudinally extending edge and an upper longitudinally extending edge. The major housing portion is defined by a 270 degree hollow cylindrical wedge. 
     A hinge 98 extends along the upper edge of the major housing and serves to pivotally connect the upper edge of the major housing with the upper edge of the housing door. 
     Positioned within the major housing portion is a foam bottle holder 90 the foam bottle holder is constructed from any commercially available foam material preferably polyurethane foam. the bottle holder 90 is securely positioned and frictionally held within the major housing portion 86 such as to not allow angular movement between the bottle holder and the housing portion. 
     The bottle holder includes a plurality of recesses 92. The recesses are specifically adapted by their size and shape to receive containers of cosmetics such as nailpolish. The apertures of the bottle holder are accessible when the housing door 84 is opened. Secure coupling of the housing portions is through lock 94. Furthermore, the hollow interior portion of the housing door is fitted with a foam section 96. The foam section 96 is curved portion to conform to the interior of the housing door 84 and an opposite planar surface serves to cover the recesses 92 of the bottle holder whenever the housing door is closed. 
     The major housing portion 86 and the housing door 84 together serve to define a cylindrical housing 18. The cylindrical housing 18 has a first end, a second end, a first aperture 102 formed centrally within the first end, and a second aperture 104 formed centrally within the second end. A mounting shaft 106 having a first end and a second end is positioned centrally within the cylindrical housing. The mounting shaft is positioned such that it extends through the first and second apertures of the cylindrical housing and the semi circular recesses 40 and 50 of the first and second uprights. A vertical bevel gear 110 is mounted upon the first end of the mounting shaft. The vertical bevel gear 110 is intermeshed with the upper horizontal bevel gear 80 of the drive shaft. 
     In use, the shaker is transported to the location in which it is desired to be used. The shaker is dimensioned to fit upon a table or desktop surface for both commercial and/or domestic use. If batteries are not used, the shaker is coupled to an external source of power. The operator then open the housing door of the cylindrical housing to reveal the plurality of apertures of the foam section. Cosmetic containers with stratified fluid contents to be homogenized are then placed within the apertures, the operator then closes the housing door. With the door closed the operator turns on the shaker and selects one of three operating speeds. When in operation, the motor transfers power through the drive shaft and bevel gear system to the cylindrical housing, thereby rotating the cylindrical housing. When fully shaken, the door is open and the contents removed to provide cosmetics ready for use and display. 
     As to the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided. 
     With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention. 
     Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
