neko.app
I was watching Systems with JT the other day and he demoed a hobby operating system called skiftOS. During the demo he ran one of the built-in apps called “neko” which looks like a clone of an old Windows “pet” program I remember from my childhood, also called “neko” (or “neko32”). It’s a really simple program: when you start it up, a cute little kitten shows up on your screen and starts running around, trying to catch your mouse cursor.
