A body has a back and parallel front. The back of the body defines an air inlet and a peripheral air outlet is associated with the front. A body chamber between the back and the front is in fluid communication with the air inlet and the air outlet. A structurally prominent faceplate is on the body proximate to the peripheral air outlet and bears a transforming aesthetic overlay. An air displacement unit is formed of a plurality of blades rotatable in a plane parallel with the back and the front. The air displacement unit is substantially concealed within the body chamber and is configured to accept air from the air inlet and urge the air through the air outlet. |
