contorted cubic

I created a cubic in 3dmax first, and then add function convert to NURBS. I select surface CV, move and play the point which can built an interesting shape and form.

The reason why I do this stage, because of I am trying to create different layers for the form. The special thing for this model is when you see form top view, front view and left view, you just see a square. But when you see the model from the perspective view , so sure you will be surprised to see a strange shape of the model.
