The object transforms into many shapes !
The torus object is constructed with many rings.It transforms flat,spherical,etc as above photos.Farther more you can reverse this torus.
If you cut torus with the plane which passes center then the section is two circles,and there are three cases.Two cases are trivial and non trivial case two circles are called Villarceau Circle(1848) .Torus Magic is constructed with many Villarceau Circles and can transform freely.
