HolyOS - making a fake operating system in Godot – Davide Di Staso – GodotCon 2025

HolyOS is my attempt at building a fake but functional '90s-style OS in Godot. I’ll show how I used Control nodes to create an instant messaging client, an email client, and a file explorer. I will also show the pipeline for the custom theme and animated cursor. To wrap up, I’ll discuss other quirks of making a fake OS feel real, as well as unresolved issues like drag-and-drop previews.

HolyOS is the fake operating system used in In Good Faith (Steam)
