You can move the dragonflies with your index fingers.

Enable your webcam to capture movements.
Position your hands in front on your camera (so between the camera and your face), with your index finger(s) clearly visible.
Move your hands very slowly. Notice the dragonflies moving with them. Try to place the dragonflies very close to each other or overlapping.
