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.

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.

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
