ce n'est pas un cuboïde 

After Magritte.

This is not a cuboid, it is a patterned woven structure in which the weave surfaces, reflecting or absorbing light in different ways, create the illusion of three-dimensionality, skeletonity or flatness, which in reality turns out to be convex ...

it is also, simply, a collection of jacquard fabrics referring to signs that have occurred in the past, such as the Japanese kikko motif, which draws its perfection from observing structures found in nature.
