Neko would follow the mouse pointer around. When cat caught up with the pointer it would stare at the screen for a few seconds scratch an itch on its body yawn and fall asleep until the pointer was disturbed. In windowed mode cat would stop at window boundaries and scratch at the edge of the window.
Schrodinger's Cat will follow your pointer. When it catches the pointer it will turn into a box and then enter. There is a 5050 chance of weather that cat will be awake or asleep after pointer is moved off the box. This is designed to be a simple amusing way to demonstrate Schrodinger's Cat thought experiment
Schroedinger's cat is a thought experiment sometimes described as a paradox devised by Austrian physicist Erwin Schroedinger in 1935. It illustrates what he saw as the problem of the Copenhagen interpretation of quantum mechanics applied to everyday objects resulting in a contradiction with common sense.
