Custom Flash Screen Saver

I need a custom windows screensaver for a client. It must be very simple, just an animation with the logo, no photos, text or anything, just the logo. Your job would be making a good looking, professional Flash animation of about 20 seconds that loops. I will show it to my client and when he´s happy, you will convert the logo to .scr format for him to install it. If would be great if you could show me some custom screensavers in your posts, but you can send other animations too.
