How To Create Great Interactive Agency "Reels"

I've been having some conversations lately about interactive agencies creating reels, just like offline agencies. Reels have the potential to be much more powerful when pitching your agency than clicking through screenshots of the sites you've created. Here are a couple examples of interactive agency reels:

• AKQA
• Cobra Creative
• Reflex Interactive

I think all are great examples of showcasing interactive work in a more dynamic manner. After all, visitors to the websites we create don't have a "screenshot" experience. Why should we give prospective clients anything less?

Here are a few tips that I can gather from looking at these interactive reels:

1. Show interaction with the website
2. Provide context by showing the complete page
3. Use Flash for reels on websites... Quicktime can load horribly slow
4. Don't use text or captions
5. Music selection is HUGE, and should reflect the type of work you do

Have any other examples of great interactive reels? Let me know.
