Judith's class from Karen (transportation)

Hi all, for my flash assignment I am going to make an online musical instrument by using the sound of different transportaion, such as the subway, bus and car. We are living in a big city, transportation is very important in our daily life, we can't go anywhere without them, but because we are so use to it, sometime we ignor the sound/noise they made, I want this project to explore the sound/nocie they've made, you will be impress by how you ignor those noise pollution
