[Kyle McDonald] sent in his latest project, a software keylogger that twitters what you type. He wrote it using C++ and OpenFrameworks. It logs each keystroke, then it posts to twitter 140 characters at a time. To protect himself, he set up a whitelist of private strings like passwords and credit card numbers that would be stripped before posting. If the twypewriter followed him, his keystrokes could be recreated.
[thanks Kyle]
