This is a plywood tree bookcase made of 6 sheets of plywood.
Nice bookcase. Did you cut each sheet separately and then laminate?
Yes I used one sheet as a templet. Nailed it to each sheet. Used a jigsaw to cut close. Then used a router with a top barring flush cutting bit. Then spread glue and nailed each sheet.
Haven't seen this type of design before if its derivative. Enjoy originality and novelty of it. Strikes me as more of a prototype with opportunity to improve as a furniture piece. Kudos for the idea and design.
