(snipped for Keanu content)
Peter Wayner's latest books are Disappearing Cryptography, an exploration about how to disguise information and Translucent Databases, a practical description of how to use encryption algorithms to protect sensitive information like credit cards and medical records. If they ever get made into a movie, he wants to be played by Keanu Reeves -- the one who played Ted "Theodore" Logan, not the one who played Neo.
