The university had a B&W flatbed scanner attached to a Mac running ... a Hypercard stack? that allowed you to scan an image and get a B&W image.
A clipart book I picked up from the college bookstore and a quick scan and I had a "logo" for the Mac shareware games I started writing in 1988 or so.
At the time I didn't;t realize how really ... nice .. Atkinson's algorithm is. But when, later, I tried dithering with other algos I saw how nice the diffusion was in Bill's code.
More recently I was playing with an eInk calendar project and wanted an "Atkinson-esque" series of images of the Moon in various phases. So I found a site very like the linked one to Atkinson-dither the moon photos I found [1].

He’s still active on GitHub though, in other repos. Maybe he will accept a pull request? :)

edit: I might open a PR. 'CoffeeScript...now there's a name I've not heard in a long time. A long time...'
It was acceptable in the 2010s
It was acceptable at the time

I've had this project gathering a light layer of dust in my home directory for a couple months now. I used Gemini Deep Research to help produce the library, and I included the LLM-generated markdown for anyone who wishes to reproduce on other languages, improve upon it, etc.
I was wondering why my Atkinson dithering web-component[0] was getting more hits today - sad news. I’ve always thought that Atkinson dithering produces the nicest images on really crisp monitors like the original Mac - something about it just looks cool and 80s which is why I used it in a game last year.

p.s. dithermark.com is super cool also.

Edit: Sorry - I misread what you were saying and intended this as a correction, but you had it right all along.
