G33kShell is a cross-platform retro-themed desktop shell that wraps a CRT aesthetic around a custom command experience.
- Boot-up BIOS prelude, login theatrics, and optional webcam face detection.
- Powered by Avalonia on .NET for cross-platform hardware-accelerated rendering with crisp pixel fonts and shader-based scanlines.
- Extensive built-in command set spanning navigation, search, system info, automation, and novelty utilities.
- Inline
manpages, persistent history, and settings that remember your favorite skins, screensavers, and working directories. - Skin system with
RetroPlasma,RetroGreenDos,RetroMonoDos, andSimpleSkin. - Idle timeout hands ownership to animated ASCII and pixel-art screensavers — many driven by AI brains you can train live.
- Navigate your filesystem with
dir,tree,cd,pushd,popd,paths, andlocation. - Inspect and manipulate files via
cat,tail,copy,rm,mkdir,find,grep,whereis, andopen. - Integrate with the OS using
reveal,space,clip,now,ver,worktime,shutdown, andmax. - Customize the experience with
skin,screensaver,man,help,history, and the CP437ASCIItable.
Tip: run man <command> for auto-generated manual pages, or help to see every command and alias.
Cycle anything you like with screensaver -l and screensaver <name>—add _train to the AI-powered ones to watch them learn in real time.

AI-enabled screensavers (asciiroids, pong, snake) store their trained neural weights between runs so you can pick up right where your last session left off.
- Install the .NET 8 SDK.
- Clone the repo and restore dependencies:
dotnet restore. - Launch the desktop shell:
dotnet run --project G33kShell.Desktop.
The application persists settings (skin, screensaver, path history, trained brains) under your user profile. Delete the settings file if you ever want a clean slate.
- Run the unit suite with
dotnet testfrom the repo root. - Avalonia assets live under
G33kShell.Desktop/Assets; screensavers underG33kShell.Desktop/Console/Screensavers. - To build your own screensaver, implement
IScreensaver, expose a uniqueName, and drop the class into the screensavers folder —screensaver -lwill pick it up automatically.
