There is something about how fishes swim around each other in the symbol of Yin and Yang. Although I have never observed this in nature, it has been well observed that fishes swim in groups and that they often swim about in ever changing direction.In my road to improving my skills in conceptual presentation, I explored the form of the Pisces as a concept art.
It started out as a concept model on 3d max.
later on, I added a few lillies and changed the colors around to better reflect the story. The base shape is now showing two fishes swimming about in a pond with water lillies around them.
This later evolved into a latticed version where it can be constructed with frames and frames of timber or steel members.
and finally, a mans eye view of this pavillion concept art.
