Lost Island for Windows

A Dynamic Island for Windows 10 and 11, written in C++ with Win32, Direct2D, DirectWrite and WinRT. It is one small `.exe` with nothing to install, and it is the Windows version of [Lost Island for Sway](https://github.com/byte4day/lost-island-archcraft-sway).

Optional: turn on Start with Windows in Settings › General.

Windows SmartScreen may warn about an unsigned app the first time. Choose **More info › Run anyway**.

1. Claude Code needs you. The Claude spark and, in orange, what it is asking ("Allow Bash?").
2. Music. Album art, title and EQ bars that move with the real output level, in the album's col
