Using numerical simulations and my original homemade scientific animations, I will describe the saga of the intergalactic ring formation. The saga is divided into three:
(1) formation of polar-rings (so called ``wedding ring''),
(2) mysterious giant ring of NGC 1533 recently discovered by HIPASS, and
(3) origin of the intracluster Leo ring.
I demonstrate that all of these (astronomically) beautiful galactic/intergalactic rings are formed from apparently destructive processes of galaxy interaction/merging (or galaxy-cluster interaction).
