Who would win? An army of dodecahedra or an army of hypercubes?

A pile of colorful geometric jewelry. Many dodecahedra on the left and many hypercubes on the right.

More progress...

A table full of colorful geometric jewelry, some of which are on cards that say Hanusa Design.

Some life news: I am planning to step back from Hanusa Design in the coming months. It has been a wonderful ride over the past nine years: learning, growing, and meeting people from around the world who enjoyed my jewelry. As I start my sabbatical year, I want to focus my attention in new ways.

I'm very happy about this collaboration and look forward to building it further over time. And many thanks to @nysci.bsky.social for arranging for these professional pictures with me and my jewelry in the shop.

Many museum shops are run by a giant conglomerate, but not the nysci Science Shop! Through this collaboration I've worked directly with Sanjay, the retail manager, who curates his store with hand-picked gift ideas. You should visit the museum and then stop by the store to see the wide selection.

There is now a wide selection of Hanusa Design jewelry on sale in the @nysci.bsky.social gift shop. Each piece has a mathematical significance, was 3D printed in nylon, and dyed in bright colors. If you're not nearby, you can shop online at shop.nysci.org. #mathjewelry

I am excited to share my collaboration with the gift shop at the New York Hall of Science (@nysci.bsky.social), an amazing science museum located right here in Queens, NY. As of Fall 2025, Hanusa Design owner Christopher hanusa (@mathzorro.bsky.social) is featured as a local artist in the shop!

Its high-time for pi-time! Check out these mini pi earrings just waiting to be assembled. So cute! So mini! (0.5 in / 12.6mm wide) So many! Order yours today: hdsn.us/NE200 #MathSky #mathjewelry #geekchic #geekgifts

The merkaba has long been a mystic symbol. At its heart is the intersection of two tetrahedra. Here is my take on this classic form, replacing the sharp lines by soft curves. Merkaba Earrings available now: hdsn.us/NE221 #MathSky #mathjewelry #nylonearrings #3dprinted #merkaba #sacredgeometry

I know, I know, it's hard to improve on the cube. But hear me out! What if you interlock two wireframe cubes together? Sure, it's crazy. But wait there's more! What if you attach a third one? And you can wear them! On your ears? What?! hdsn.us/NE210 #MathSky #cubes #nylonjewelry #3dprinted

Red earrings made out of three dangling cubes

Forbidden subgraph earrings - wear a theorem on your ears! Kuratowski's theorem says that a graph is planar if and only if it contains neither a K5 nor a K3,3 as a subgraph. Here are those two forbidden subgraphs. Available at hdsn.us/NE230. #MathSky #mathjewelry #gomath

Hi! I turn mathematical ideas into wearable art. I design #mathjewelry 💍 using computational software, bringing them to life through a 3D printing process (SLS nylon or lost-wax casting). Free US shipping over $99. Visit hanusadesign.com to see the full collection. #MathSky #mathart #smallbusiness

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?!?!? 🧊🧊 Koch Tetrahedron: hdsn.us/ME234 Read more: hdsn.us/read 🧮 #mathjewelry

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! hdsn.us/rotini #MathSky #mathjewelry

Two red cylindrical earrings with swirly patterns on a white background.

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). Earrings: hdsn.us/ME218 Pendant: hdsn.us/SS110 #mathjewelry #MathSky

And since it's already March 2 in many parts of the world, I'll share mathematical jewelry on a three-dimensional square grid: 3D Plus Earrings, made up of seven cubes. The grid structure provides gives different views from different angles. hdsn.us/NE206 #mathjewelry #MathSky #MathArtMarch

Maroon, Red, Yellow, Teal, Blue, and White 3D Plus Earrings arranged haphazardly on a white background.

Hanusa Design @hanusadesign· Mar 2

What great prompts! I have some jewelry that fit many of these words; I'll see if the other topics inspire new pieces. Day 1 of #MathArtMarch is my Circle Around Pendant, featuring circles of circles! hdsn.us/MP414

Here we have before the bath and after the bath... Or should I say the #aftermath?! #mathjewelry #MathSky

The same nylon 3D printed jewelry, dyed blue

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