Ribbon lamella surface

Hi there,

I want to make a ribbon lamella surface as a facade of the Messe Basel new hall from Herzog &de Meuron. I am not sure that my logic is correct since it looks a little bit different and I do not know how to adjust the rotation degree in different parts as the picture shows.
Can anyone help me figure out that? Or It has a simple way to make this shape?
Thank you!

Did you look at this link?

Hi Laurent, Thank you for your replying. That was very helpful. After I viewed Kim’s blog, I made one by myself, but I still have some questions.

I just think the ellipse is the effect of a deformation of the surface (not flat).
Here your definition with a not flat surface

Th other thing could also be a deformation of the surface and an opening depending on the angle of the surface. Many possibilities.

Thank you! I think you are correct!
