blurlock is a simple screen locker for X that blurs the current screen content before locking it.
This provides a visually appealing and secure way to prevent unauthorized access to your screen when you step away from your computer. Unlike traditional screen lockers that simply display a solid color or image, blurlock provides context, allowing you to recognize if something unexpected is on your screen while still obscuring the sensitive content.
It's particularly useful in environments where privacy is a concern, such as public spaces or shared offices. Blurlock uses the `xlock` command to handle actual locking and authentication after blurring the screen.

blurlock depends on tools such as `xlock` and libraries for image manipulation. You might need to install packages like ImageMagick, although the exact requirements may vary based on your system and the blurring method employed.

The appearance of the blurred screen can be customized by modifying the number of blur iterations (-n) and the blur intensity (-i). Experiment with these options to find a balance between security and visual clarity.
