MODEL

With this model, I was able to create a lighting effect:

It's a question of a space that supports the ideas of the models it comes from. Clearly three areas can be distinguished. The first one of them, most opened, with entry of direct light. The different thicknesses together with sloping planes provide different heights in this area which is seen reducing increasingly up to coming to the second place. That one is very narrow and dark since it does not receive direct light. 
Finally, In the last place we meet a wider area with major height compared to the previous ones, whose only illuminated part comes directly from the roof, staying the rest of the surface reflected with the above mentioned light.
