I like to listen the BBC Iplayer while I work. However, they repeat a lot o stuff, so sometimes I need a new source of spoken words. Over the last couple of days I have been listening to the cosmic computer from LibriVox. Librivox has volunteer people reading aloud books in the public domain.
The cosmic computer was about a search for a big military computer hidden on a world. It was interesting book -- mostly because it explored macro economic ideas (a little bit) anyway.
