Starting from a simple square I create 16 3D models. Each number corresponds to a level of height. The number zero instead corresponds to the absence of the level. If you pay attention to the model "1234" you can see that it is a pyramid with steps, while the model "0000" is the same pyramid but it is concave. I hope you are going to like it and thank you for watching.
