xeyes

xeyes is the legendary X Window System demo program that renders a pair of animated eyes following the mouse cursor as it moves across the screen. First created in 1988, it remains a beloved Unix desktop classic.

Features:

• Animated eyes that track cursor position in real time across the entire desktop
• Uses the X SHAPE extension to display transparent, non-rectangular window geometry
• Configurable eye outline colors, pupil colors, and update intervals
• Minimal system resource consumption
• Nostalgic desktop companion and visual cursor locator for multi-monitor setups
