Charles Armstrong at Trampoline Systems emailed me this offer:

to mark next week's sentencing of jeffrey skilling (former enron ceo) we've launched a website where you can browse 200,000 enron internal emails from 1999-2002. powered by trampoline's sonar platform, "enron explorer" generates visualisations of each executive's social network and analyses the thematic content of their correspondence.
