Using a hand held fan to beat the heat is a common sight. Having a message splayed on spinning fan blades would be eye-catching & an interesting endeavour to advertise in a casual but flashy way. Writing out a message will not only make people pay attention for longer but the speed of the display to state the message can be adjusted to fit any criteria. This means that the message could take a certain amount of time before fully displaying the message & then another action could be done such as rotation. A relief from the heat & a hearty message that could be seen.
