Dukno Yoon, a metalsmith and jeweler from Kansas creates spectacular rings, bracelets, metronomes, and other machines that mimic the movements of flying birds. Here’s a statement from the artist:
“The contrast between metal structural form and natural feather, together with the repetitive and whimsical movements of fragile wings, provokes the imagination and evolves the intimate relationship between work and viewer/wearer.”
Yoon has put a LOT of work into creating these designs. The sheer number of accessories that he’s created is pretty astounding, and you can find all of them here.
