Do they release any software? It’s frustrating when Brett Victor tells us how modeling our protagonist’s path during development is a boon for the developer … and refuses to release even a demo. I can read (and hear) about things Ink & Switch have explored, but can we experience that, too?

I love the ideas these folks explore. I also want to explore - but I don’t have the time budget to learn and implement their concepts. I can’t speak for other software engineers, but I am much more likely to improve on such work if I can experience it first.

Automerge started as a research prototype and is now a widely-used substrate for building local-first apps: https://automerge.org/

Our GitHub has a boatload of experiments: https://github.com/orgs/inkandswitch/repositories

This is a fun afternoon just waiting for you: http://feelingisreality.com

Muse started as a research project and turned into an app: https://museapp.com/

Some of our essays have embedded versions of our prototypes you can play with:

Alex Warth is currently working on a remake of Ivan Sutherland's Sketchpad: https://github.com/alexwarth/sutherland

There's probably a bunch more I'm forgetting.

They do! https://github.com/inkandswitch

And Ivan's is here. https://github.com/ivanreese

But "public release of hest" was a joking reference to the fact that he's stated quite clearly that the project is just a testbed for him and will never be released. (No matter that every once in a while it makes the rounds of sites like this and everyone goes a-twitter...)
