Important Notes for Windows:
- Start your X server (VcXsrv/X410) BEFORE running this script
- In VcXsrv: disable "Native opengl" and enable "Disable access control"
- If GUI doesn't appear, check Windows Firewall settings
- Docker Desktop must be running

echo "Done! The turtle window should appear in your X server."
