An SDL2 port of the classic screensaver after analysing its binaries with REA (bring your own copy).

The full story
This is an unofficial Linux port, using SDL2, of the "Mystery" haunted-house screensaver from Microsoft Plus! for Windows 95: lit windows, an owl, bats, a black cat, a creaking door and a howling moon. A --wide mode fills modern 16:9 and ultrawide screens without black bars.
It was built after analysing the original binaries with REA, and you supply your own Mystery.dll. The author is upfront that all the code was written by Claude through Claude Code, steered in plain language and checked by eye, with no human review or formal audit.
