Significance of the different designs of Tobi's/Obito's masks


There have been three designs of the masks of Tobi/Obito shown in the Naruto
(anime/manga). Is there any significance behind the masks and the designs, or
is it just a design and something to be ignored?

The masks in each stage has their own significance:

The **Spiral Mask** with center at the eye was designed by the mangaka to give
the **dimension switch** by Tobi a better look.

The **Rinne-Sharingan** shaped mask was worn by Tobi during the Shinobi War to
represent his mission i.e achieving the Rinne-Sharingan for the **Infinite
Tsukuyomi** .

All these designs don't have any significance from the perspective of the
storyline. They were just designed by the mangaka to have a stylish,
appropriate appearance.
