very cool, worked exactly as expected.
great landing page and demo, value proposition is very clear and the demo works exactly as expected.
thoughts:
1. that title bar takes up a LOT of valuable screen real estate, pushing some of informative content below the fold -- don't need quite as much title space
2. draw more attention to the "demo" links. Its easy to miss the link as is. The demo is great, takes 2 seconds only, and was very convincing. You should want EVERYONE who makes it to the landing page to convert to a demo.
