By analysing the paper "Choosing Scotland's Future" by counting the frequency of words in the document and printing those words in a font size in proportion to their occurence then it is possible to produce this 'word cloud' to get a handy view on what the main themes/topics might be.

Jonathan Harris' latest project, Universe , really has to be tried to be believed. Perhaps its the future of news gathering? He has produced software which trawls news sources across the web and clusters, tracks relationships, organises and presents stories in an imaginative and dynamic interface. You can use it here, try typing in a topic and epxlore. For an explanation watch Jonathan's presentation to the TED conference earlier this year, where he also demos his work on "We feel fine" - software which monitors blogs around the world (in English) to identify every mention of the phrase "I feel".
