+## Windows 11 (cross-compiled from Linux)
+
+A self-contained `vectorgons.exe` can be cross-compiled with the
+**MinGW-w64** toolchain. It statically links GLFW and the GCC/threads runtime,
+so on Windows it needs **only system DLLs** (`opengl32`, `glu32`, `gdi32`,
+`user32`, `shell32`, `kernel32`) — just copy `vectorgons.exe` to a Windows 11
+machine and double-click it. No console window, no extra DLLs.
+
+```sh
+# 1. toolchain:  sudo apt install gcc-mingw-w64-x86-64 binutils-mingw-w64-x86-64 mingw-w64-x86-64-dev
+# 2. GLFW:       download the WIN64 binaries from https://www.glfw.org/download
+# 3. build:
+make windows      WINCC=x86_64-w64-mingw32-gcc GLFWDIR=/path/to/glfw-3.4.bin.WIN64
+make screensaver  WINCC=x86_64-w64-mingw32-gcc GLFWDIR=/path/to/glfw-3.4.bin.WIN64
+```
+
+The legacy immediate-mode OpenGL it uses (and the `glu32` perspective helpers)
+are provided by the standard Windows OpenGL driver, so it runs on any Windows 11
+box with working GPU drivers.
+
+### Screensaver (`vectorgons.scr`)
+
+`make screensaver` builds the **same program as a Windows screensaver** (it's
+the same source with `-DSCREENSAVER`, output named `.scr`). It handles the
+standard screensaver command line:
+
+- **`/s`** (or no argument) — run full-screen on the primary monitor; **any key,
+  mouse click, or real mouse movement exits**. The on-screen control panel is
+  hidden.
+- **`/c`** — show a short configuration dialog. There are no in-saver controls;
+  the saver simply uses whatever settings the main app last saved (see below),
+  so run `vectorgons.exe`, dial in the look you want, quit, and the saver picks
+  it up.
+- **`/p`** — preview (the little monitor in Windows' settings); not supported, so
+  it exits cleanly and the preview stays blank.
+
+To install on Windows: right-click `vectorgons.scr` → **Install** (or copy it to
+`C:\Windows\System32` and choose it under *Settings → Personalization → Lock
+screen → Screen saver*). Like the `.exe`, it needs only Windows system DLLs.

+- **Magnifying glasses** are real lenses. After the field is drawn, the back
+  buffer is grabbed into a texture (`glCopyTexSubImage2D`); each lens body is
