A Linux tool that grabs exclusive control over keyboard and mouse input by displaying a fullscreen black window with a hidden mouse cursor. It also streams random data into named pipes in /dev/shm/*.pipe as part of its operation.

- Linux system with GNOME desktop
- Python and
pipinstalled gnome-terminal(used to run the app script)python-xlib(installed automatically)
- The Bash script detects dynamic named pipes in
/dev/shmand launches background processes writing random data into these pipes. - The Python script connects to the X server, grabs keyboard and mouse input exclusively, and creates a fullscreen black window with the mouse cursor hidden using Tkinter.
- Keyboard and mouse events are blocked from reaching other applications, effectively locking user input to this fullscreen window.
- When the window closes, input grabs are released, restoring normal system input behavior.
