Pyy the Platypus — the Slim64FS mascot

Meet Pyy. The crash-safe platypus.

Pyy is the mascot of Slim64FS — the crash-safe filesystem for removable flash media. This is the official home of Pyy goods: plushies, shirts, stickers, and other things that survive being dropped.

Section 01

Why a Platypus?

A platypus is nature's oddball composite: a duck bill, a beaver tail, fur, venom, and eggs — from a mammal. On paper it should not work. In practice it has shipped continuously for millions of years, surviving every environment it was dropped into.

Slim64FS is the same idea in software: an unusual combination — a filesystem written by AI under strict human governance — that should not work, and then survives a 310-trial crash matrix with zero corruption. Pyy is that spirit with a bill on it.

Pyy keeps things simple, the way the filesystem does: write once, verify, go idle. No drama while the light is blinking. If the battery dies mid-nap, Pyy recovers to the last committed nap.

The engineering lives at slim64fs.org — specifications, crash matrices, and audit ledgers, all public. This site is the fun half: putting the platypus on things.

Section 03

Two Halves, Two Licenses

The project is deliberately split. The engineering is free forever; the character pays for the plushies.

The code — MIT, forever

Slim64FS

The filesystem — every line, every spec, every test log — is released under the MIT License at github.com/slim64fs/slim64fs. Zero legal friction: camera companies, embedded vendors, and hobbyists can adopt it without a licensing conversation. Buying merch never becomes a requirement for using the software.

The character — all rights reserved

Frequently Asked Questions

When can I actually buy something?
Production is being lined up now, starting with the items that draw the most interest email. Click “Notify me” on anything you want — you will get exactly one email when it becomes available, and nothing before or after.
Does buying merch support the project?
Yes — proceeds fund Slim64FS development, test hardware (the media matrix does not buy its own SD cards), and hosting. The code itself stays MIT and free regardless; merch is the way to chip in that also gets you a platypus.
What is Slim64FS?
A crash-safe, CRC32C-verified filesystem for removable flash media — SD cards, USB drives, NVMe — engineered with AI under human governance and verified through relentless testing. The full story, specifications, and evidence live at slim64fs.org.
Why a platypus?
Because a platypus is an improbable composite that works anyway — which is also a fair review of a filesystem written by AI. Also, Tux was taken.
Can I use the Pyy artwork in my own project?
Not without permission. Unlike the Slim64FS code (MIT), Pyy's artwork and character are all-rights-reserved trademarks. For licensing requests, contact admin@slim64fs.org.
Where will you ship?
Shipping regions and costs will be announced per item when it goes on sale — that is part of what the interest email decides. Tell us where you are when you write; it genuinely affects the plan.
