• This is really an interesting way to use the sim for a real-life applications 10/02/07 Trish Loeblein
• This is a nice demonstration. It could be simplified by removing the 3 "speaker cone" walls. The "plug" will still perform the same function. You can also use a plug in the water and light tabs. 10/02/07 Noah Podolefsky
• From Steve Pollock: "a neat use of the "adding a wall" feature of the sim, which I had never noticed before!" 10/02/07 Trish Loeblein
