From the developer:
DashLock is a widget that adds a little lock to your Dashboard. The widget allows you to lock your screen quickly and switch to the login window, keeping your session active. It is very straightforward to use DashLock. You just click on the lock and after a short animation, your computer will switch to the login window while keeping you logged in.
