Hanusa Design mathematical jewelry is excited to share our collaboration with the gift shop at the New York Hall of Science (), an amazing science museum located right here in Queens, NY. As of Fall 2025, Hanusa Design owner Christopher Hanusa () is featured as a local artist in the shop!

There is now a wide selection of Hanusa Design jewelry on sale in the nysci Science 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.

Many museum shops are run by a giant conglomerate, but not the nysci Science Shop! Through this collaboration I've worked directly with Sanjay Lakhani, 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.

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?!

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.
