The Romans left behind over a hundred mysterious bronze dodecahedra, and nobody knows what they were for. I can't solve that, but I can fill one with spirals: 12 pentagons, five corners each, chasing inward. A tiny galaxy on every face. ✨ #generativeart #mathart #creativecoding

If a disco ball studied geometry. 🪩 A sphere cut into 320 triangles, each one filled with a curve of pursuit: corners chasing corners, all the way in. #generativeart #mathart #creativecoding

Before and after: one is a coloring page, the other is what happens with a little time and a lot of color. 🎨 Choose your petals and rings, then click to see what appears. Print it for quiet coloring time, or color it right on your screen: lifeislinear.davidson.edu/mandala-make...

A Monday pause before the week takes over. Watch one ring turn. Breathe in, breathe out. Then another. A small, endlessly spinning start to your day. #CreativeCoding #MathArt #GenerativeArt #MondayMood

This starts closer than the Louvre will ever let you get. How fast do you recognize her as it zooms out? (Or did "Louvre" already give it away?) 🌻 #CreativeCoding #MathArt #GenerativeArt

Taught the flower to bloom. 🌸 Think of it as a time-lapse: half the day it spins left, half the day it spins right, and in between it rests. Tomorrow it starts all over again. #generativeart #mathart #creativecoding

Grew a flower with zero water and about 600 triangles. 🌸 A pentagon cut into 10 slices, each slice's corners chasing each other inward. Neighbors spin opposite ways, and petals appear on their own. #generativeart #mathart #creativecoding

Update: they're still chasing. 🔥 Same rosette, now animated: 60 pursuit curves winding up from bare outlines and back again, on loop forever. #generativeart #mathart #creativecoding

Everyone here is chasing someone. Nobody ever catches up. A curve of pursuit: each corner of a shape steps toward its neighbor. 60 little chases in 12 petals, and the glow is just where the lines pile up. inspired by @helsig.bsky.social's posts #generativeart #mathart #creativecoding

When two photos become one… Not Photoshop—linear algebra! A linear combination of two image matrices creates something entirely new. #MathArt #LinearAlgebra

Plot twist: every line in this portrait is a polynomial. Sometimes mathematics reveals the bigger picture—if you’re willing to step back and look. Can you see the hidden image? #MathArt

They say a picture is worth a thousand words. This one brings the idea full circle. Look closely: the portrait is made entirely from concentric circles. Create your own mathematical mosaic at: lifeislinear.davidson.edu/circleArt.html #MathArt #MathematicalMosaic

Me: builds an image generator where Tetris pieces fall into place to form a picture Also me: realizes halfway through that the pieces just phase through each other like ghosts Ship it anyway. 👻🧱

My code plays "Tetris" with your photos — squares that are "close enough" in color just... merge. No falling pieces, no line clears, just an image slowly collapsing into blocks. 🟨🟧🟫

Adaptive mesh refinement in a mosaic. Got the idea off a wall pattern during a meeting!

Tim Chartier @timchartier.bsky.social · 15/09/2026
The pattern on a wall during a meeting caught my eye and I had an idea to mesh refine based on variation of the color in a mosaic's tile. Each triangle in this mosaic is a solid color.

Zooming in on a daylily reminds me that complexity often hides in plain sight. Sometimes the most interesting patterns only appear when we look a little closer. #photography

Sometimes the best photos aren’t about finding the perfect flower. They’re about noticing the conversation happening between two of them. #photography

This flower clearly skipped the “less is more” design meeting… and I’m all for it. 💜💛 #photography

Fireworks may last a few seconds. Mathematical patterns last forever. I traded fireworks for curve stitching. Different kind of spark...same sense of wonder. 🇺🇸✨ Happy 4th of July weekend. #MathArt

Zoom in and you see circles. Zoom out and you see a cardioid. Mathematics often rewards changing your point of view. #MathArt

One algorithm. Infinitely many possibilities. Today's waiting room became a playground for curve stitching. Same program. Different parameters. Endless exploration.

Hoping this keeps the watermelon from turning every curve into an adventure and a melon-dramatic situation.

Marvelous Mathemagic with Art Benjamin at @momath.bsky.social on Pi Day. A bit irrational but I wish the show had gone on forever.

The new @momath.bsky.social is entirely stunning. It’s a living celebration of curiosity, creativity, and the joy of discovering math in motion. Everywhere you turn invites a new way to play with an idea.

Was watching the Game of Thrones spin-off and saw mathematical designs. Decided to try one. This isn't what I saw but what I made AFTER I made what I saw!

Went out to eat, saw a pattern on a tapestry, took a picture, and came home and replicated it in python! Gracious!

PEMDAS isn’t about memorizing an order—it’s about avoiding chaos. Bob the Counting Sheep gets a visual explanation (with a little help) of why order matters in math. More sketches at Math Figures: www.youtube.com/@mathfigures... #iTeachMath #MathEducation

What does it mean to get     closer and     closer and     closer to zero without arriving? In mathematics, approaching can matter—even without arriving. More sketches at Math Figures: www.youtube.com/@mathfigures... #iTeachMath #MathEducation #MathArt

Zippy thinks he’s good at math because he’s quick. A second grader shows him where he went wrong. Speed isn’t understanding. Thinking matters. Videos appearing at: www.youtube.com/@mathfigures...
