Whether seen in a science museum or inside a physics classroom, everyone is intrigued by a wave machine. One can watch and observe the periodic motion of a mechanical wave machine in amazement without knowing that 30 minutes just passed by. Prepare yourself because you are about to observe a virtual wave machine ... only now you (not the museum official or your teacher) are in control. You can set it vibrating at any frequency and any amplitude you wish. You can even view it simulating a sound wave. Watch it vibrate in slow motion. Watch it in fast motion. Watch it in real time. And watch the clock because you're going to be so captivated that you might be late for your next class.
