This is a script where links(A tags) falls from the top of the page and to the place where you have placed them in your HTML code. The content is pure HTML which means that it's search engine friendly.
You can customize the script by increasing or decreasing sliding speed. You can also choose to reverse sliding order, i.e. start with last item instead of first item.
The script is HTML based. This means that you don't have to worry about detail works such as x and y positions of your falling items. All this is taken care of by the script.
