Roll down 728x90 banner

[sunroof]

Hello,

Do you know how can I make roll-down 728x90 banner in Flash. The banner should be normal 728x90 banner, and when the user mouseovers it the banner rolls down over the site content. Banner will be published using Google Ad Manager...

Any ideas?

Thanks

Could you use JavaScript to make another flash file with a transparent background appear when the original banner is moused over?
