|air projecting blinds
A projector projects a still image taken from still fans that, when moving, blow air onto blinds. In front of the blinds are the fans represented in the still image. The air from the moving fans closes the blinds. Live-stream video from a camera recording the fans projects onto a wall behind the blinds where the blinds block the air from the fans. The air from the fans becomes visibly unfelt.
The moving fans become screens where the still image projects a still fan. The fan looks still but blows air onto blinds from the front of the blinds.
