Caterpillar is eaten by a worm, although not literally. The construction giant Caterpillar has had its computer systems hit by the Zotob worm which has been targeting Windows 2000 software. Also in the programme, one Chinese activist is imprisoned for blogging about the government, the importance of web diaries, and how one doctor has developed an inexpensive DIY endoscope, using a computer and a colour printer. Presenter: Gareth Mitchell.
