In the realm of traditional origami, cutting techniques are generally less common. However, they are very promising methods for creating pop up ads or lampshades. 3D books use this technique to make storybooks quietly popular. This shows that storytelling can be enhanced by pop-up folding. When unfolded, a pop-up butterfly or sheep can be quite attractive. But why is it visually appealing? This might be because the transformation of a flat sheet into a three-dimensional shape mimics basic life movements, allowing the eyes to capture more information, I suppose.
