Xneko displays a window in which a cat chases your "mouse"
cursor. Try moving the mouse inside and outside the xneko window,
leaving it stationary, moving it slowly and quickly, etc., and watch the cat
respond.
All options except the last three above behave in the standard
manner for X applications (see X(1)). The -speed option
controls the speed of the cat (the default is 16). The -time option
controls the interval (in microseconds) between updates of the xneko
window (the default is 125000). The -help option provides a usage
message and exits.
The program was originally written by a Japanese author as a
Macintosh desktop accessory (The word "neko" means "cat"
in Japanese).
