Peter Griffin prank (Rust remake)

A tiny prank desktop app: a borderless 397x319 window shows a Peter Griffin image and a Close button. The button does not close anything — it opens 50 windows (800x450, same image stretched) at random positions on screen, one every 100 ms, until the desktop is buried.

This is a Rust port (eframe/egui) of an original .NET WinForms executable (Peter.exe). Window sizes, image placement, the "Close" button and the 50-popup volley match the original; popup placement is now randomised instead of stacking.

Run it

The manifest holds the whole story:

install = "cargo build --release"
run     = "bin\\peter.exe || bin/peter || cargo run --release"

nd run <slug> shells that out (sh -c on Unix, cmd /C on Windows), so:

nd run peter-griffin-prank      # prebuilt binary for this OS
cargo run --release             # force a source build

How the chain resolves:

| Shell | First branch | Result | |---|---|---| | cmd (Windows) | bin\peter.exe | runs the Windows build — backslashes are required: cmd splits bin/peter into command bin plus switch /peter | | sh (Linux/macOS) | bin\peter.exe → binpeter.exe | not found (one harmless line), falls through to bin/peter, the native ELF | | either, no prebuilt | cargo run --release | builds and runs from source (needs rustc 1.95+) |

Windows without Rust still works — the first branch never needs cargo.

Prebuilt binaries

| Platform | File | Notes | |---|---|---| | Linux x86-64 | bin/peter | needs GL/Vulkan, X11 or Wayland | | Windows x86-64 | bin/peter.exe | Windows 10+ (UCRT), DirectX 12 or Vulkan |

They can also be run directly. Both were verified locally: the Linux one natively, the Windows one under Wine (window appears at 397x319 as expected).

Build from source

Requires rustc 1.95+ (the eframe/egui 0.37 family declares that MSRV):

rustup update stable
cargo build --release          # -> target/release/peter
cargo run --release

Cross-compiling the Windows build on Linux

Needs a Linux-hosted MinGW-w64 toolchain (Debian/Ubuntu: gcc-mingw-w64-x86-64; Arch: mingw-w64-gcc + mingw-w64-binutils, which also provides the x86_64-w64-mingw32-dlltool that rustc needs for the windows crates' raw-dylib imports). Zig's bundled MinGW is not enough — its sysroot lacks libpthread.a/msvcrt that Rust's windows-gnu link line expects.

rustup target add x86_64-pc-windows-gnu
cargo build --release --target x86_64-pc-windows-gnu
cp target/x86_64-pc-windows-gnu/release/peter.exe bin/peter.exe
cp target/release/peter bin/peter                   # refresh the Linux build too

Release builds use the Windows GUI subsystem (#![cfg_attr(not(debug_assertions), windows_subsystem = "windows")]), so no console window appears.

Notes

• The main window is borderless and centred on the monitor at startup.
• Popups get explicit random positions. Wayland compositors ignore client-requested window positions, so the app hides WAYLAND_DISPLAY/WAYLAND_SOCKET at startup to make winit use X11/XWayland. Set PETER_KEEP_WAYLAND=1 to keep native Wayland — popups will then be placed by the compositor (usually all in the same spot).
• There is no network, filesystem or persistence code; the app only creates windows.

Layout (taken from the original WinForms forms)

| Element | Geometry | |---|---| | main window | 397x319, undecorated, centred | | face image | (12,43) 373x171, stretched | | "Close" button | (149,273) 75x23 | | popup window | 800x450, title "Form2", image stretched | | popup timing | 50 windows, 100 ms apart, random positions |
