If you have javascript disabled you won't be able to see the demo. Also if you're using Safari, the local.live.com Javascript API does not work so you won't see it either.
Use the StartPanning link to see the flyover effect. You can also step through the flyover in stages. Feel free to use the javascript. It's pretty simple to use, with config values set away from the code. The code works in IE6, Firefox and Opera.
Last weekend I walked most of Mt. Snowdon. The next day I wanted to show some friends where I went and what route I took. It was a pain panning through the whole route so I wrote a ton of javascript using the Virtual Earth API to do it automatically.
