I created a flash application named ScrollbarGenerator.
This free utility let's you generate the CSS code (Cascading Style Sheet) that will customize the color of Internet Explorer scroll bars.
Only Internet Explorer version 5.5 or higher for Windows support this customization. This handy web design utility lets you preview and create the proper code even if you don't use internet explorer or if you aren't using the windows platform.

It's a good idea, and a great tool . . . but won't validate. But I'm sure you already knew that.

Don't alienate people because they don't have flash player 7. I'm sure there's a way you can export it to play in lower versions (forgive me if I'm wrong).
It's nice though - well done.
(Now we're going to have an influx of newbs asking why it doesn't work in Firefox . . . )
