I've just listened to this Livescribe recording of Sir Ken Robinson talking at the Creativity World Forum in November. It was recorded by Shannon, one of the educators from Canada we met at the conference, using her Livescribe smartpen.
This is a fascinating device that allows you to record and keep notes simultaneously, then publish them to the internet. It's certainly not cheap but I like the fact that analogue note making can be connected to a search-able, digital parallel recording that can be published and shared with others. I also like the way the 'Pencast' is interactive when viewed in full screen mode. Presumably the cost of these pens will eventually come down, making them more accessible to the average student and teacher.
