I've published Macstodon, my silly little Mastodon client for Classic Mac OS to GitHub: https://github.com/smallsco/macstodon

I'm not providing any support or planning any serious development or maintenance of this, it's just a fun little hack project. Please fork and extend :)

Some Gotchas:
- You need MacPython 1.5.2 installed to run it, because my Mac crashes when I try to compile it into a standalone app.
- You need some kind of SSL stripping proxy running on another machine, I recommend WebOne: https://github.com/atauenis/webone
- It only posts plain text toots and doesn't have any other features
- There's no error handling. Expect crashes!
