I'm developing diagrams for a new edition of my book on H.264/AVC. I've been experimenting with hand-drawn vs. computer-drawn diagrams. I quite like the immediacy of hand-drawn diagrams. Here are a few examples - I'd like to have your opinions on these. Please leave a comment (or send me an email) with your views - do you prefer hand-drawn or computer-drawn?

The examples are in this file:
