One of the biggest production users of Ohm that we know of is Shopify.
They used Ohm in the Liquid HTML parser that powers their prettier plugin & VS Code language server — as well as the Shopify Admin's CodeMirror-based editor.

The Ink team at Ink & Switch is starting something new — publishing our internal lab notes.
These are (mostly) unedited, with all our puzzling and musing and prototypes unfiltered.

We’ve begun publishing the internal research notes we write within the lab. Some of these newly published notes come from our archives of past projects, others are being freshly written about our latest work. Be aware that these are notes we write for ourselves. Sometimes they’ll mention a term or name that you won’t be familiar with. Many notes link to other notes that aren’t public (yet?). If you’re interested in our quest to build a dynamic notebook with programmable ink, or are working on something similar yourself, there’ll be lots to see and learn here.

What if a spreadsheet cell could hold multiple values at the same time?
That's the idea behind Ambsheets, a project I've been working on w/ @geoffreylitt.com at @inkandswitch.com. It's a new spreadsheet that makes it easier for you to explore many possibilities simultaneously.

Logic Game, 2005.
I made this logic circuit simulator to learn Etoys, Alan Kay & co.'s programming language for kids. I represented the state of the wires and logic gates with their "costumes" -- there is no hidden state. This makes the behavior of the circuits visible.

Used my Ohm JS harness to design & implement a little programming language for Finite Cellular Automata and then shipped it as a toy into Patchwork.
It's really cool to be able to work on a little programming language and pop out to change the syntax without even reloading my browser.

Sketchpad: the "dismember" operation inlines an instance into the drawing it's in. This lets you mess with its lines, etc. without changing the master.
In this demo, I make two instances of drawing #2 and dismember the one on the left. The one on the right stays whole.
