An active display device includes a motorized base and a transparent display. The base unit includes a magnetic drive, which communicates magnetically with a magnetically attractive rotor or agitator in the bottom of the display unit to circulate the fluid within the display unit and any particulate matter mixed therein. The purely magnetic communication between base and display eliminates all mechanical passages therebetween, thereby precluding potential leakage routes from the display component and permitting the display to be readily removed and replaced atop the base. The display may include a magnetically movable floor or other panel, if desired, with the floor panel disposed between the magnetic rotor and the display having a series of passages therethrough to permit liquid circulation, but precluding passage of particles beneath the floor to the rotor area. The base may include numerous additional features, such as an audio system, remote actuation, lighting, etc.
