This stool is called rotation as the origami support structure like rotating. It is like something that transfers from the bottom to the top. With the different angle of perspective and light, it shows different shape.

Inspired by Japanese origami, this structure is more stable than expected. It also can store something when opening the top cover, which applies one more function of the stool. With circle top and bottom, it also can be rolled like a car when moving the stool.
