Sometimes its better to show than to tell so I thought I'd have a go at recording one of my demos of the new user interface in Office 12.  It is recorded with only 16 colours so it will look a lot nicer in real life.  I'm attaching the spreadsheet that I used in the excel 12 demo in case you have beta 1 and fancy doing this demo yourself.
I think the sound went a bit dodgy in the word section for a few seconds but it recovers.  If people like the idea, I'll look at doing more of these so let me know.
