About:
Xeyes is a classic X Window System utility that displays a pair of cartoon eyes which track the cursor's movement across the screen. It demonstrates the X SHAPE extension by using a non-rectangular window mask to render the eyes and pupils. While primarily a fun demonstration of X11 capabilities, it also serves as a useful tool for verifying input device functionality and window manager behavior.

Key Features:

Real-time cursor tracking with animated eye movement
Utilizes the X SHAPE extension for non-rectangular window masking
Low resource usage and minimal system footprint
Configurable appearance through X resources

Use Cases:

Demonstrating X11 graphical capabilities and extensions
Verifying mouse input and window manager functionality
Providing visual feedback for remote X11 sessions

Alternatives:

xclock – Standard X11 clock utility; less graphical but more functional for timekeeping
xlogo – Displays the X Window System logo; similar demo purpose but static
