An air circulation system-driven, suspended rotating display device includes an attachment member and a rotatable member. The attachment member has an upper end and a lower end, and a component for attachment proximate a ceiling fan or, alternatively, proximate an air vent. The attachment component is located at the upper end, and has a swivel joint for attachment to a rotatable member. The rotatable member has a frame, a sign connected to the frame and at least one air vane connected to frame for acting like a turbine to cause circulating air to spin the rotatable member with its sign.
