Shere Khan Black Hand is a mouse theme designed for X11 software, featuring a distinctive black hand cursor.
For those who might be wondering what X11 is, it is a windowing system that implements the X display protocol and provides windowing on bitmap displays. It is often referred to as X and is primarily used to build graphical user interfaces (GUIs) on most Unix-like operating systems and OpenVMS. Furthermore, this protocol has been widely accepted in many other general-purpose operating systems.
X serves as a basic framework or primitives for building GUI environments. It can draw and move windows on the screen and interact with a mouse and keyboard. It does not mandate the user interface; hence, individual client programs handle this.
One significant advantage of X is that it has network transparency. X can be accessed over a network connection from different machines, even if the display server is not on the same machine as the application program. This feature has made X a valuable tool for remote computing.
The X protocol first appeared in September 1987, approximately three years after MIT developed it. Today, X has undergone significant development, and the X.org foundation leads the X project. The current reference implementation, X.org Server, is also available as free software under the MIT License and similar permissive licences.
In conclusion, if you are looking for a visually appealing mouse theme that provides easy access to your system, then Shere Khan Black Hand is worth trying. Moreover, gaining a better understanding of X11 will enable you to build more robust GUIs and operate remote systems with ease.
