Another screenshot, this time from Episode 1 of the Dirk Gently TV series . There are several pencils in this episode. One of them is easy to identify and plays an important role: it’s being used for shading paper to reveal a message.

The TV series seems to be loosely based on the book, with different episodes picking up different plots from Douglas Adams’ book (at least that’s the impression I have so far, after watching the pilot and episode 1. Future episodes might be different).
If you want to know more about Faber-Castell’s Grip 2001 pencils have a look at pencil talk’s review. There’s also another review at Pencil Revolution.
Update: 11 March 2012: Today would have been Douglas Adams’ 60th birthday.
The photo of the pencil has been taken from episode 1 of the Dirk Gently TV series. I believe that the use of this image falls under “fair dealing” as described by the UK Copyright service.
