Tweetpad
I introduce the tweetpad, a paper-based Twitter interface, for those of us who occasionally take a break from technology, but who still want to record 140-character fragments of their day.
Features:
- Pocket size
 - 140 characters, with emergency overflow line
 - No batteries required
 - Mac‑, Windows- and Linux-compatible
 - Helvetica Neue
 
Soon to be available in a Java version, which has an uglier font, is more difficult to print out, and requires you to sellotape the pad to a large brick to make it work.
