I don't think cubism can represented in 3D models this way. Cubism is a way to represent an object from many perspectives on a 2D plane. That's why the faces of cubist subjects have both a profile and frontal view. This artist really needs to find a 4D subject to represent in 3D. That would be closer to the spirit of cubism.
I agree... Even more than 3D, cubism intends to interpret time and movement. Nevertheless, I liked the approach of the artist and it's certainly a new perspective.
