Martin Sejer Andersen's Golden Palm Box
Folded from a hexagon cut off from a square of 25 cm on the side of Japanese wrapping paper.
When I first saw a picture of this model, I thought that it was just another heaxagon box made out of a hexagon twist, but it turned out to be much more than that. What is more interesting in this model is not its top but its bottom.
