Vibration Tutorial v0.1.0

Downloads

Standalone builds need no Python install. Download the one for your system, unpack it and run it.
They are not code-signed, so the operating system warns the first time you open one.

System	File	How to run
Windows 10/11 (64-bit)	vib-tutorial-*-windows-x64.zip	Unzip, then run vib-tutorial\vib-tutorial.exe. If SmartScreen says "Windows protected your PC", click More info → Run anyway.
Linux (x86-64)	vib-tutorial-*-linux-x86_64.tar.gz	tar xzf vib-tutorial-*-linux-x86_64.tar.gz, then run vib-tutorial/vib-tutorial. Needs an X11 or Wayland desktop.

On macOS, or if a build doesn't run on your system, run from source with
uv instead: uvx --from git+https://github.com/WookieLumberjack/vib_tutorial@TAG vib-tutorial,
with TAG replaced by this release's tag.

This software is for educational use only, with no warranty; see the README's disclaimer.
