After clicking the Green Flag... Click on the screen.... to let the computer draw pin wheels (on the place that you are clicking). After placing three, sit back and watch the wind turn them.
100 % pen (except for the pencils). Thanks to @PinkyPepper for the inspiration and the challenge to make the pin wheels spin. Thanks to @Scratch-Minion for the "rotation-around-a-point" Trig calculations.
