Two small fans sit on a white surface against a plain background; the fan on the left is a standard rotary fan, while the fan on the right is a "Tuna Flapping Fan" with two flexible fins that flap up and down as it operates. The text overlay changes from identifying the left fan as a "Quiet" Rotary Fan to the right fan as a "Tuna Flapping Fan," and the audio specifications for the right fan change from 13db and 570hz to 7db and 50hz, indicating a quieter, lower-pitched operation.
