Many Thanks to yoosklondonsummit user PatNInterrupt for highlighting the site Many Eyes for us. Many Eyes allows people to make visualisations of either text streams or data sets.

This is just a quick example of what can be done - the potential is there for much more interesting visualisations to be made and I'm looking forward to trying this out with a few Gordon Brown and David Cameron speeches.
