9Locker v1.0.2

描述：9Locker is a screen-lock utility for Windows that unlocks a screen with a pattern tracing action. You can unlock the computer using a pointing device by tracing out a pattern on screen. It supports touchscreens. It even has the ability to e-mail you if somebody tries to unlock the screen and fails, and can even send a webcam video attachment showing the perpetrator. There is also the option to include an alarm sound. In the case of a multi-monitor system, all non-primary monitors will just go black.
