I can across this link today: http://www.sadena.com/BBC-Radio/H2G2/
Its the entire collection of the Hitchhiker's guide radio plays (the first season predates the book). It's proven to be a delightful listen so far.
On another note, my work colleague Jakub, was telling me about his DVD collecting habbits. Every friday he buys a DVD, usually spending €10. If he spends more than ten euro, he waits two weeks to buy another. Taking his advice I started doing this myself. DVD no. 1 is Frost Nixon (expect a review in the coming days)
