Kamiyu 3.5, by Satoshi Kamiya

The almighty Ryujin 3.5 designed by Satoshi Kamiya and folded from standard 15cm x 15cm Kami. 64 sheets of it to be precise, each folded into a 12 x 12 grid by the attendees of the 2023 Lyon ultimate origami convention. The pile of sheets was then bodged together with transparent tape and folded into one of the biggest origami collaborations in history, containing the names and creases of folders from all over the world.
