The archive

A decade of a cat that was never on the payroll. Everything filed here carries a label saying what kind of thing it is, because a documented fact and a good story should not look alike.

The entries

Three kinds of entry live here and they are not the same thing. Every card says which it is.

Documented history
Recorded outside this project. Each one links the source it can be checked against.
Project statement
Something NINJACAT says about itself. True by declaration, not by external record.
Narrative
Fiction, written for this archive. Set in monospace inside a dashed rule so it never reads as a fact.

    Documented history

    The ninja cat becomes a Windows in-joke

    A cat riding a fire-breathing unicorn spread through Microsoft as an unofficial emblem of the Windows 10 era, appearing on stickers, shirts and internal art. It was never an official mascot — that is precisely what made it beloved.

    Narrative

    NINJACAT.EXE

    A terminal-styled narrative written for the archive. It is fiction, it runs entirely in the browser, and it downloads or executes nothing.

    Written for this archive. Not a documented event.

02Narrative

NINJACAT.EXE

A short piece of fiction kept beside the archive rather than inside it. It is text on a page: nothing is downloaded, nothing is executed, and leaving it closed costs you no information.
