At least one liquid exhibiting variable visual effects is disposed in a transparent chamber and is moved in variable, turbulent flow patterns by a magnetic member freely movably disposed on the bottom of the chamber. A magnet is mounted on a rotatable output shaft of a drive motor disposed adjacent to the bottom of the chamber and is magnetically coupled to the movable member to move the movable member in a chaotic, variable pattern to generate variable liquid flow within the chamber. The speed of rotation and the direction of rotation of the motor output shaft at a selected speed are variably selectible.
