About
Hi, I’m Yu Yoshimuta, a builder based in Tokyo.
I explore how AI can become a natural part of the way people think, create, and work.
I try to listen closely, question my assumptions, and learn from people who see the world differently from me.

Notes

A short note on turning four flat patterns into one navigable three-dimensional object.
Today I finished the first version of this portfolio. It begins with one three-dimensional sculpture that resolves into four graphic patterns from four different viewpoints.
Hope you'll enjoy it:D
