Sorry for the very abrupt previous post. Sometimes, I'm not sufficiently verbose and I am in a hurry to jot things down. I do hope that there were some tools that you had a heads up on. Whilst on The Bleeding Edge Forum (at which I am one of the administrators), I was looking at an introduction to Mozilla's Ubiquity that Stephen posted.
I was impressed with the clarity in the first few minutes of introduction and good use of simple, clear, large type, animated to drive ideas across. Have a look at it and think what you could do with your next PowerPoint presentation.
