Abstract
A fan structure includes a fan head having a plurality of blades mounted for rotation. A mechanism is coupled to the fan head and is constructed and arranged to move the fan head along a surface of a sphere in a three dimensional pattern. At least one motor is constructed and arranged to cause rotation of the blades and movement of the mechanism. The mechanism thus provides both back-and-forth and up-and-down motion of the fan head.
