In addition to the aluminum sheet cut by the utility knife, I also tried the factory cut model with 2mm aluminum sheet. The appearance is very delicate, no matter the cutting edge or the hollow part, no additional processing is required, and the weight is very light. Overall it will be one of the materials I consider.
-What to do with the shadow?
In fact, I have always been observing the shadows created by the windows grille, but in the previous unit, I focused too much on the creation of shadows and gradually deviated from my theme. However, in the aluminum sheet photo 1 and 2 , I found that multiple light sources can cause shadows to overlap. This result is very similar to the plastic wrap experiment I did last unit (picture below), so I plan to explore the shadows that light from multiple angles can create.

Since I personally don't have a clearer shadow photo, I used Stefano Perego's photo as a perfect demonstration of shadows from window grille.
