Hidden about the photo montage are a number of hot spots. Move the mouse over the montage until you find one. When you find a hot spot, click the mouse and you will hear a short audio clip related to the image you have clicked on. You may have to wait a moment before the audio begins to play. It helps to have a high-speed Internet connection. If you are browsing with Firefox, you probably won't be able to hear the clips.
If you are in a public setting, be warned that one audio clip contains profanity.
