The work
Trying building more in public this year.
First up: a React library for building macOS-style windowed desktop environments in the browser. Real multi-window management, menu bar, system tray, desktop icons, virtual file system — the full OS shell, in ~80 KB total.
Grew out of a bigger project I've been working on. Figured it might be useful to others.
