Found some Yosegi process images showing the joined-block construction technique similar to how we are making some of our jewelry pieces. This process allows for a sculpture that is lighter in feeling and lends itself to those mesmeric geometric elements. We tend to geek out on this kind of stuff.
"Yosegi uses rich woods to produce complex geometric patterns.
Yosegi-Zaiku means yose = collect, put together; gi = wood (to make) zai = small, sensitive: ku = work.
Thin wood pieces are combined as a surface, or assembled using solid wood to form the patterns. The pieces are glued together into basic units and then cut and placed together to make a continuous pattern."
