People can feel the roughness and smoothness of objects by touch. At the same time, it is also possible to see whether the object is smooth by the movement of the object.
A smooth object can move very quickly. A object is too rougher to move harder. So I want to express the roughness of the object by the movement of the object.
In order to combine the two objects I choose the way to rotate. Because a smooth object wants to move, it is limited by a rough object, and by rotating it can make a rough object move very fast.
