Lock Your Desktop With A Translucent Screen 
ScreenBlur enables you to keep your desktop private with a password protected screen overlay or a Desktop Blockout option, which will temporarily mask your wallpaper, shortcuts and gadgets to hide them from prying eyes. You can choose to lock your screen automatically after X minutes of inactivity or whenever you press a user defined keyboard shortcut. The translucent lock screen allows you to keep an eye on open windows or applications, which preventing others from messing with your computer. If you want additional privacy, ScreenBlur can automatically minimize all open windows and hide desktop icons and gadgets while your screen is locked. Other features include an option to mute sound while the screen is locked, multiple lock screen designs, adjustable lock screen opacity (for more or less privacy), automatic lock on restart, and more. Please note that ScreenBlur is not designed to provide hacker-proof desktop security. It adds privacy and can cat-proof or kid-proof your desktop, but advanced users will probably find a way to bypass the lock screen.
