One embodiment of a fan assembly includes a housing having a base member and a lip member extending outwardly from the base member for defining an enclosure. The fan assembly may further include a toothed track assembly, a wheel assembly, a first motor, a second motor, and a fan member. The toothed track assembly includes a toothed track member disposed within the enclosure. The wheel assembly includes a pair of toothed wheels adapted to move on the toothed track member. The first motor is operatively coupled to the wheel assembly and is capable of rotating the pair of toothed wheels. The fan member is coupled to the wheel assembly, such that the fan member moves along the toothed track member when the first motor rotates the pair of toothed wheels on the toothed track member. The second motor is operatively coupled to the fan member for rotating the fan member.
