This model is just a tessellation of Crossed Box Pleats: the back side which you see here is the Crowding Butterflies model by Shuzo Fujimoto. You can notice that this model can also be seen as tessellated Hydrangeas (level 1) with reduced inter-molecule spacing. I folded this model as a base for another tessellation, but I liked it so much I thought it was worth a picture. I think the decorated border I added also adds to the effect.
Folded from one sheet of Ogawa Washi (see my review of this paper).
