Definition
Neko is a small, animated desktop companion program that depicts a cartoon cat which chases and interacts with the user’s mouse cursor on a computer screen.
Overview
Originally created for the X Window System, Neko has been ported to various operating systems, including Microsoft Windows, macOS, Linux, and several mobile platforms. The program runs as a background process and displays a graphical cat that follows the cursor, attempts to catch it, and performs a series of short animations (e.g., walking, jumping, sleeping). Neko is often distributed as freeware or open‑source software, and it has inspired numerous clones and derivative projects that implement similar “desktop pet” functionality.
Etymology/Origin
The name “Neko” (猫) comes from the Japanese word for “cat.” The original implementation was released in the early 1990s; however, precise details about the initial author and exact release date are not fully documented in widely accessible sources. Accurate information about the original developer is not confirmed.
Characteristics
- Platform compatibility: Initially designed for X11; later versions exist for Windows (compiled with Win32 APIs), macOS (using Cocoa), and various Unix‑like environments.
- Behavior: The cat’s animation logic is based on the relative position of the mouse pointer, with simple state machines governing walking, jumping, catching, and idle actions.
- Customization: Some forks allow users to replace the cat sprite with alternative graphics, adjust speed, or modify the set of animations.
- Resource usage: Neko is lightweight, typically consuming a few megabytes of disk space and modest CPU cycles, making it suitable for continuous background operation.
- Distribution: The software is frequently packaged in Linux distribution repositories under names such as “neko” or “xneko.” Windows binaries are often provided as downloadable executables from third‑party sites.
