CSS/HTML scrolling text without scrollbars

all!

I need to make effects with like on the picture. I can make text shading (transparent imgage on top and bottom of a text) but I have no idea how to make scrollable text without scrollbars and clipping (overflow: hidden). Have eny idea?

I have only one idea - add image over scrollbar to hide it from users

Try this out:

<div id="container" style="width: 183px; height: 183px; overflow:
hidden; border: solid black 1px">
<div id="floating-div" style="width: 200px; height:200px; overflow:
auto">
Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.
