On Friday at Noon (EDT) I am giving a talk in the New York Combinatorics Seminar. The title is: "Mathematical illustration through a combinatorial lens" in which I share my decade-long journey as a mathematical artist and jewelry maker and how it intertwines with my combinatorics research.

The show went great! It was so nice to be able to share the pieces with everyone. Lots of excitement and enthusiasm for the designs. And everyone else's work was amazing!!

I was fortunate to receive a large order; so I can share with you the five metals I offer at @hanusadesign.com side-by-side!

Top row: silver and brass. Bottom row: rhodium-, rose gold-, and 14k gold-plated brass.

This is my popular Möbius necklace, available at hdsn.us/MN328.

Day 5 of #MathArtMarch is discovery. What do you get when you build a 3D analog of the Koch snowflake? Start with a tetrahedron and add smaller and smaller tetrahedra to the boundary. Keep going and you get ... a CUBE?!?!? 🧊🧊

Four earrings arranged in a square. The earrings are made up of tetrahedra but make the shape of a cube.

#MathArtMarch for 3/4/25 (nice numbers btw!)

"swirly" ... that made me think of my rotini earrings. (pasta ftw!)
Each model swirls to replicate a different mathematical function. From left to right: |x| (x+sin(x)) sawtooth, x^2, x^3, e^x

They're so fun!

The #MathArtMarch prompt for 3/3 is "Nature". This made me think about the cute honeycomb earrings I designed to go with my honeycomb pendant. They're a mixture of geometric (hexagons) and organic (generative Voronoi).

And since it's already March 2 in many parts of the world, I'll share mathematical jewelry on a three-dimensional square grid:

What great prompts! I have some jewelry that fit many of these words; I'll see if the other topics inspire new pieces.

what if circle theorems were actually just sick graphic eyeliner ideas all along?

I like dyeing with blue dye because it always feels like playing with a magic eight ball!

Hello, BlueSky! I’m Alena, I like slugs! I make slug art and sell sluggy nifty-gifties! That’s the elevator pitch 😂

An illustrated poster of 10 different sea slugs from the west coast of North America, in different shapes and rainbow colours, over a blue background.

A photo of two stickers. The top one shows a yellow banana slug with text that reads “Weird Is Wonderful.” The bottom one shows a green pacific chorus frog with text that reads “This Frog Is Proud of You.”

8 different enamel pins are displayed on Alena’s hand. The pins are of a Belted Kingfisher, Bull Kelp, Leaf Sheep Sea Slug, Pacific Banana Slug, Pacific Sideband Snail, Sea Bunny Nudibranch, California Banana Slug, and an Opalescent Nudibranch.
