Working on slides for my next talk...

AutoScarf update: the app works, the crochet pattern works, we are ready to roll once we get the website together! If you love 2-color reversible crochet and custom cellular automata algorithms, sign up to hear more and join the project at forms.gle/G8rWQVccZ4MM... #crochet #geek #math #awesome 🧶

Cover art for the May 2026 issue of the Notices of the American Mathematical Society. Here's a link to the issue: www.ams.org/notices

I converted a text message into a knight's tour. To decode it, follow the knight's tour, starting in the top left corner. The knight will traverse a succession of 11x11 tours, and each of these 11x11 tours corresponds to a letter. The message is a quote from Ursula K. Le Guin.

New project in the thinkin’ stage

The last stitch isn’t an exciting explosion, it is just a stitch. The project completes quietly ♥️💙 www.grannylifecrochet.com @crochet @mathart @done 🧶

The final artwork is coming together! One side is “night” and the other is “day”. grannylifecrochet.com 🌙☀️

Pulling up loops at the corners to attach the work to the backing fabric. Will weave in the long ends to stabilize the edges… www.grannylifecrochet.com #grannylife #mathart #geek #crochet 🧶

Geordi, Is there a way to enter our authorization codes by typing them instead of speaking aloud to the computer? Several crew members have complained that they need to memorize a new code after each use because coworkers overheard them. Worf

This is cellular automata applied to a staggered grid, like in beaded peyote stitch. All of these images were created with the same algorithm, what I call “Vines on a Fence.” The only difference among them is how I started each patch. I give the recipe for Vines on a Fence on page 105 of my new book

On the way to Paris on the Eurostar and finishing the second-to-last join row of the “blue side” of the Granny Life community artwork www.grannylifecrochet.com

The “red” side of the Granny Life artwork is done!! granmylifecrochet.com #crochet 🧶

Finally have the squares split into two halves each with 11 stacks and can start assembly! www.grannylifecrochet.com

Hey #JMM2026 find me wandering around or at the Monday night Knitting Circle if you want to crochet a square based on a cellular automaton for a math/art/community exhibit www.grannylifecrochet.com

Granny Life update: About 160 squares here, sorting into a two-sided design. Expecting 50 more in the mail soon, need a few more. Deadline now Jan 8 to get a square to me if you want to join the project and have your work be part of an art exhibit in Paris! #math #crochet 🧶www.grannylifecrochet.com

Uh oh I have fallen behind 😫

Did I spend all day coding instead of doing the things on my long end-of-semester to-do list? Yes. Is my app cooler now? Also yes. mathgrrl.com/simultaneous...

Can you find 11 simultaneous 11-queens solutions? I wrote a little app to search for them. There are regular solutions (each row shifted), but I'm looking for one that is more interesting. Maybe it doesn't exist? Press the button and see if you can find it :) mathgrrl.com/simultaneous...

Granny Life update: The new arrangment will be an 11x11 grid of squares arranged using 11-queens solutions and latin square conditions. I made a little app to find examples: mathgrrl.com/simultaneous... ⚡Also: Still time to claim squares to crochet for this project at www.grannylifecrochet.com !

Getting so many squares for the Granny Life project that the piece is now going to be two-sided. Had to make up a new whip stitch to get the attachment right. @crochet 🧶 Still time to claim squares and be part of the art at www.grannylifecrochet.com !

@mathgrrl.com I’m enjoying making squares for the Granny Life Project. Here’s a diagram that I made of what the basic stitch layout looks like if you want to make your own design, or if you want to color in what you’ve crocheted as you go along for your Granny Life square.

Still time to join the Granny Life community math/art project at www.grannylifecrochet.com ! My job is assembly, so today I am learning about braided fishing wire and how to tie fishing nets. Hoping to incorporate a strong net grid into the project. It's going to weigh about 15-20 pounds!

My friend showed me this daily web game: Which Year? It shows five photos, and you have to guess the year for each one. You can get four free digits with no penalty, but each digit can be used only once (in other words, you can get the thousands, hundreds, tens, or ones each only once). whichyr.com

At the TMiP conference in August, we announced the winner of this year's MEGA Grant - Christian Lawson-Perfect will be creating beautiful aperiodic tilings in the sand, as part of the #BeachSpectres project. Christian's write-up is here: aperiodical.com/2025... More info at http://tmip.uk/mega-...

Wonderful tilings all over the place at LaGuardia airport!

Getting back to this WIP to prepare for Bridges Galway deadline! Game of Life “pulsar” oscillator with concentric rings for simultaneous time step visualization

🎉🧶🇫🇷 The community project "Granny Life" is going to Paris!! The artwork was accepted for the exhibit "Création, entre arts et mathématiques" at Maison Poincaré in Paris. Woooo!!! Join the project and your crochet can go to Paris too! www.grannylifecrochet.com

This is blame I'm happy to accept. Authors, check to see if you're eligible to receive compensation in the Anthropic Settlement and if you are, file that claim. secure.anthropiccopyrightsettlement.com/lookup

Next part of the layout for the www.grannysquarecrochet.com project. Trying to keep things balanced with local strategies: put similar colors a knight’s move apart rather than same row/column, keep similar patterns away from each other, try to bring down bright colors using neighboring colors

Blocking squares for the www.grannylifecrochet.com project. Ready to receive more squares!

Yesterday's Granny Life crochet-a-long inspired 2 new "pro tips" for making beautiful squares: 1. Twist the yarns just before the corner 2ch, to make it easier to catch carried yarn later. 2. It helps to make your hdc crochet stitches a little "tall". www.grannylifecrochet.com/pixie-square... 🧶

Create crochet granny squares for a community math/art project! Our Granny Life motif-generating app can now export printable pattern pages ❤️ www.mathgrrl.com/granny-life @geek @crochet 🧶

Progress Report! Squares claimed and in progress: 86 Squares that have been crocheted: 30 Squares that have been received: 22 Squares attached to the artwork so far: 9 Join the community crochet cellular automaton project at www.grannylifecrochet.com

After trying a lot of local rules for symmetry and other things, in the end I think the best strategy is to make sure things that are close together don’t have colors or patterns that are (1) too similar or (2) too different (?). Thoughts on arrangements? www.grannylifecrochet.com

Thinking about this type of join for the www.grannylifecrochet.com project, what do people think? This is just an extra round of 2hdc clusters with join-as-you-go. #grannylife #crochet 🧶

Neat discovery: Two knots whose connected sum has an unknotting number less than the sum of the unknotting numbers of the knots. This provides a counterexample to an old conjecture.

IFComp has started, and my game, Phobos: A Galaxy Jones Story is part of it! Check out all the games at IFComp.org!

Granny Life Progress Report! Out of 100 squares needed, 6 are completed and 54 more are claimed and in progress! Still 40 squares left to claim if you would like to join the cellular automata community crochet math/art project at www.grannylifecrochet.com #geek #mathart #grannylife #crochet 🧶

Just came across this guy on tiktok who plays connect4 with random people on the street and I know it’s a joke, yet this person is doing more to ground himself in his environment, connect (ha) with the people around him, while getting the people he plays with to take a micro break in their day 🥲

Math nerds and crafty geeks! You are invited to crochet a granny square based on a cellular automaton for the Granny Life project at www.grannylifecrochet.com. Your work could end up in an art exhibit in Paris! There are plenty of motifs still available to claim :) #mathsky #crochet 🧶

I've signed up for @mathgrrl.com 's amazing #grannylifecrochet project at www.grannylifecrochet.com. I'm not a granny and I've never crocheted but this looks like a great opportunity to take part in mass participation maths algorithm based art. What's not to like? Squares still available!🇫🇷🧶

Great Etsy shop by @clairezagorski.bsky.social, love this window sticker! www.etsy.com/listing/1484...

Wrote some code to check when Rule 6 starts repeating; luckily it takes a while, to Generation 1407 -- which then resets all the way back to Generation 1 in the next step! #grannylifecrochet www.grannylifecrochet.com www.mathgrrl.com/granny-life
