Inspired by our love for the His Dark Materials series, we created an alethiometer that answers any query in the form of a cryptic emoji reply. Powered by celestial Dust and earthly JavaScript.


A short screen recording of the app, with the copy cropped out for some reason.
The Golden Compass / His Dark Materials series shaped me in my adolescent years in ways that are hard to even put into words. What a great thing about life that I’ve met other people for whom it’s done the same, many years later.
I had wanted to make a silly little emoji version homage to the alethiometer from the series for a while, but didn’t know how to develop a mobile app. So I pitched it to Bad Idea Factory in 2017:
Project Haiku:
You ask the compass,
“How am I going to die?”
It answers, “🦉🍞.”
Project Analogy: It’s like an emoji Magic 8 ball for people who read the His Dark Materials trilogy
Project Description:
The His Dark Materials trilogy is centered around a “Golden Compass”. Its official name is alethiometer, or “truth measure”. The device is like a compass, in that it’s the size of a pocketwatch and has needles that spin toward answers. Its face shows 36 symbols, each of which can represent 12+ ideas, concepts, or literal meanings.
To use the compass, the user sets the three needles to three symbols that frame the question she is posing, and then the alethiometer spins the needles to three symbols to provide a cryptic answer. This answer is truth, but must be carefully interpreted.
I would like to create a mobile app that replaces the 36 alethiometer symbols with emoji. The answers the app returns to users’ queries will be almost completely random, but shrouded in the symbology of the novels, it’ll be really hard to prove that.
There’s an emoji equivalent for each symbol on the compass. (Twitter’s open sourced emoji collection may do it, but is two years out of date, so we may need to purchase the license to use Emoji One’s updated collection).
Bylaw Questions
How is this project a bad idea?
This project takes a beloved fantasy novel’s central artifact and makes light of it with inane emojis. Furthermore, the logic behind the app’s “truth-telling” will be fairly random, potentially opening us up to lawsuits when someone misinterprets their answer and does something stupid.
If this project were a D&D Character, what alignment would it be and why?
Rebel (chaotic good), because it “follows [its] own moral compass, which, although good, may not agree with that of society.” Source.
Where are the lulz?
Fans of the Dark Materials books may actually enjoy having a Golden Compass app to play with, and the emoji symbols correctly set expectations for the nonsense answers we’re likely to return.
How does this project make people thinking face emoji?
When the user asks the Emoji Compass a serious question, they will be provided a reply with a (unbeknownst to them) random array of emojis. The wide range of potential symbolistic interpretations will allow the user to infer meaning where there was none to begin with, not unlike reading into lyrics to a song, or the punchline of a New Yorker cartoon.

Who made it happen:
Lou Huang heroically volunteered to build the thing, despite never having read the books. Lou did watch the 2007 Golden Compass movie to (successfully) troll the book stans.
We tweeted out a call for help with the visual design, back when Twitter was good, and the amazing designer Margo Dunlap, also a fan of the books, replied and volunteered.
Margo produced an iterative series of designs to bring the compass, its dials, and the atmospheric backgrounds (Lyra’s Oxford and the celestial Northern Lights) to life in a manner that somehow managed to find balance between a smartphone’s flat graphic design and the atmospheric Dust of the books.
Dan Schultz developed an open source app wrapper, helpfully named “iOS virus,” that can take any website and turn it into an iOS app.

I (Matt Stempeck) generally worked with everyone here to make the project happen, and mapped the set of contemporary emoji to the symbology of the alethiometer. I researched their meanings to write concise, cryptic future-telling script for each symbol:

Chris Peterson, whose tattoo of Lyra with alethiometer wins him ‘most committed His Dark Materials fan’, leaned on his crippling hyperliteracy to pen a beautiful letter to the series’ author, Sir Philip Pullman, presenting the project:

Mike Tigas helped me enclose using the Bad Idea Factory wax seal on a trip to New York.

We got the letter to a friend in Oxford, who got the letter to a colleague, who we understand got the letter to Sir Pullman. We never heard back, but we also never got sued, so…success??
Reception: We launched on iOS in 2020. The app went on to gain fives of delighted users, and despite launching not long after HBO’s prestige treatment of the series, was never acquired. It possibly informed a brief social media campaign by the official account for the show.
More backstory:
On a trip to Oxford, I got to visit Lyra and Will’s bench (spoiler alert on this link) in the Botanic Garden, not far from June 24th:

“There was an ornate gateway, with stone seats inside, and while Mary and Serafina sat there, Will and Lyra climbed over the iron fence and into the garden itself. Their daemons slipped through the bars, and flowed ahead of them into the garden…There was a massive stone wall with a doorway in it, and in the further part of the garden the trees were younger and the planting less formal.
Lyra led him almost to the end of the garden, over a little bridge, to a wooden seat under a spreading low-branched tree.“Yes!” she said. “I hoped so much, and here it is, just the same…Will, I used to come here in my Oxford and sit on this exact same bench whenever I wanted to be alone, just me and Pan. What I thought was that if you – maybe just once a year – if we could come here at the same time, just for an hour or something, then we could pretend we were close again – because we would be close, if you sat here and I sat here in my world -“
“Yes,” he said, “as long as I live, I’ll come back. Wherever I am in the world I’ll come back here – “
“On Midsummer’s Day,” she said. “At midday. As long as I live. As long as I live …”
He found himself unable to see, but he let the hot tears flow and just held her close.”



On the same trip, I enjoyed finding a whole series of historic compasses and other arcane scientific devices in the History of Science Museum:
