Just move your mouse over the links above to start the example. The onMouseOver and onMouseOut methods are used to activate the appropriate function to clip the layers. As a suggestion, you'll probably want to make the speed of the clipping faster when you exit than when you enter the layer. That tends to make the code more "fool-proof". Also it's best that you use greater than and less than symbols to define when the layers get clipped. If you don't, then sometimes if you switch between layers too quickly it'll mess up - like one will get clipped half way while the other one starts and so on.
