A collatz creature code doodle at the end of a busy week: codepen.io/fractalkitty...

National Math Stars has posted a position for their Pathfinder program. I enjoy working with this lovely group of people and mentoring Stars. #mtbos nationalmathstars.org/careers/

My friend needed a friend #mathart

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!

I composed an OP-1 track and wrote a coded poem: www.fractalkitty.com/somewhere-he... #codedPoem #op1 #poetry #creativeCoding #cleanCode #proceduralArt #music #Synths Thanks @r.whal.ing for the encouragement.

A new inquiry activity is posted on Fractal Kitty! www.fractalkitty.com/inquiries-we... This one plays with graphs and can be used as an extension to Sim, Don't Make a Triangle, and other such games. #mtbos #iteachmath #mathplay #accessibleProofs #inquiry #turan #graphTheory #triangles

Mathober in this weeks CodePen Spark! It was a really fun month of math doodles. codepen.io/spark/480 @codepen.io #mathober #mathober2025

Once we ran out of candy - which was way faster than expected, I'd say 9 out of 10 trick-or-treaters were elated to have origami paper. The rest were happy with rocks. One group needed to see a noperthedron There was an occasional fidget toy or math toy coming of the printer that went out as well

#mathober Day 31: central. Led me to central dilation which led to #spiral similarity which led to #geogebra... www.geogebra.org/m/wcqcuq3s

I like to close #mathober with some calaveras to remember those we lost this year from the math community. Chief for me was the amazing Shelli Temple (druinok). www.tumblr.com/mathhombre/7... #mtbos

#Mathober code is complete! On codepen: codepen.io/collection/y... On OpenProcessing: openprocessing.org/curation/90042 #mathober2025 Thank you Everyone that participated - It was so inspiring to see all of the are, posts, humor and creations.

Today's #mathober is Minor. I used minor arcs: codepen.io/fractalkitty... #mathober2025

Have you noticed a change of colors? 🍁 You can now define colors in the 3D calculator that depend directly on coordinates. 📝 Learn more in the Desmos Help Center: help.desmos.com/hc/en-us/art... #iteachmath #mathsky

I've got one more #mathober post - today's prompt is "recursion", and this by-hand construction of the Spiral of Theodorus seems sort of recursive. Just keep adding triangles over and over. The length of the hypotenuses are the square roots of 2 through 17 […] [Original post on universeodon.com]

Found a bluesy geogebra jam on YouTube for the hexyl triangle today while thinking about #mathober www.youtube.com/watch?v=Gc9R...

Today's mathober: codepen.io/fractalkitty... #mathober2025

An article on aphantasia: www.newyorker.com/magazine/202... I often was too told to picture mathematics and it took me a long time to realize that other people actually could.

🌈 😃 Now you can now define colors in the @Desmos 3D calculator that depend directly on coordinates. www.desmos.com/3d/42d0f0d88f

For #mathober day 27:bidiminished I tried for a Parabidiminished Rhombicosidodecahedron in Polypad. Will not fold :-( polypad.org/tjsbVJj9afVOVQ Diminished means substituting a regular polygon fo a feature like a cupola.

Forgot to post this: #mathober day 25: wedge which led me to ungula and a bit of #geogebra. www.geogebra.org/m/nbyrdhcv

My 14yr old is learning blender. He already has a space capsule, rocket, and launch sequence. But this detail made my morning.

I didn’t get to Margie’s prompt today. I went down a musical doodle wormhole. I’ll post tomorrow

Quick doodle for #mathober Day 23: Jacobian. www.tumblr.com/mathhombre/7... You see Robespierre was a Jacobin...

Hope I did this right. Here is the Jacobian for #mathober today: codepen.io/fractalkitty... Thanks to Dr. Poulsen for the link on Mathostodon. drspoulsen.github.io/Onion/ #mathober2025

I think I love Odious Numbers. #mathober #mathober2025 #mathart #p5js codepen.io/fractalkitty...

#mathober Day 22: Odious. www.tumblr.com/talkingnumbe... #mathcomic

I had to look up today's #mathober prompt, "odious", to see what it meant in a mathematical context. I learned that an "odious number" has an odd number of 1's in its binary representation. Then I wondered if anyone had extended that to other number bases […] [Original post on universeodon.com]

Check out the animated shader on Demosky!

#mathober2025 Day 18: Primitive Going for a sort of virtual particle animation for this one! This one is very poorly optimized. Made on #demosky

Today's Mathober: codepen.io/fractalkitty... I was going to do more with the planes, but decided after a long run and a good day I needed to hug my banjo instead. #mathober2025

Forgot to share yesterday's code for #mathober Domain: codepen.io/fractalkitty... #mathober2025
