In my case, I am not using the original flat wall to form a space but several little cubes .It is a definition that form the whole from individual part. The cubes capture subtle lighting effects to add the sense of organisation or hierarchy. All parts are individual but connected. They are linked with each other by some sequence.
I am not putting them together optionally. There is an order when I putting each individual one on another. Like it smaller at left and becomes bigger as it goes right. The order should fit the esthetic principle and also consider about the shadow it form.
Something kindof messy turns into something shows the order and consistency, this is what I want to have in my model. It really gives some architecture thinking when I was doing this.
