Color Changing Scrollbar
This is a simple script that can be used to change the color of the scrollbars on your page. They cycle through the colours of your choice. This script is easily customizable. The colours in the effect can be changed by changing the colors values in the switch statement. The speed can be changed by changing the second parameter in the setInterval function.
Example:     See the Scroll bar
