Japanese Joinery Bookshelf

I found a bookshelf online that uses no screws, no nails, no glue. Just interlocking wood joints that hold together through friction and geometry. I've been thinking about it for weeks. Visible at every corner, the joints look like puzzle pieces. Protruding tabs slot into matching grooves on the adjacent board, so the construction method doubles as decoration. Each connection uses a different style: dovetails on top, finger joints on the sides, wedged tenons on the shelves. Variety makes it clear the builder was showing range rather than picking the easiest option. Unfinished walnut, the grain shifts direction at every joint. You can see exactly where one piece ends and another begins. Close looking rewards you here. The further you zoom in, the more detail you find. The density of craft makes it feel like it was built for a specific person. I want to learn how to make joints like this, but even watching tutorial videos makes the precision clear. Measurements are in fractions of a millimeter. It holds about 40 books and feels solid enough to survive being moved. Because it can be disassembled and reassembled without tools, it could last through multiple apartments. Longevity is built into the joinery itself. The connections don't degrade the way glued or screwed joints do over time.
