To explore different ways of communicating ideas online, I've recently been experimenting with making graphics-driven 'video talks' to stick on YouTube (although the most recent is an actual filmed thing). They are deliberately quite short and quite fast, as preferred by YouTube viewers. If you like, please give them star-ratings and add comments.

David Gauntlett's inaugural lecture from November 2008, reduced to a 10-minute presentation of the key points.
