PROBLEM TO BE SOLVED: To provide a performance device capable of giving healing and imagination to a person sensorially perceiving it by producing a fantastic space. SOLUTION: The performance device 1 uses a wall face W of a dark room and a translucent screen 2 disposed in front of the wall face W as a projection surface, takes a picture of a ball B in front of the wall face W by a video camera 5 and outputs it as position information; a control device 4 generates a group of butterflies 1a and scales 1b moving to approach the position of the ball B as a display picture based on the position information; and a video projector projects it on the translucent screen 2 so as to project it on the wall face W transmitting through the translucent screen 2.
