Lufutu OS

PetDock is a pixel duck that lives on my Mac desktop. It wanders across the screens, sleeps, quacks, and now and then runs at the mouse and steals the cursor. Hover over it too long and it gets cross.

It's made in Godot. The first version kept leaving "zzz" floating in the air when the duck was woken up, so I moved its behaviour to LimboAI.

Later I let it listen to coding agents (Cursor, Claude Code): when the agent edits a file or runs a command, the duck says something short. That part became The Unexpected Agent, under the MIT licence.
