Re: Bobtastic's Iwagumi Scape

I must admit that I don't really understand most of the "principals" of iwagumi or the "Golden Ration" for that matter!
The 'principles' of Iwagumi are either observations by Amano of rock formations in nature or rules that were laid down in Buddhism that were adapted by him. Sometimes the Buddhist 'rules' are more symbolic and less naturalistic like 'this stone is a tortoise, this stone is a representation of a Buddha, this gravel is the sea' or can also be a more stylised version of nature so Amano bought these down to earth to agree with his Nature Aquarium ethos.
Simply put The Golden Ratio was something the philosophers of Greece found out from calculations that coincidently compositions in nature normally lie in proportions of roughly thirds or a ratio of 1:618. They then went mad for it and used it to work out proportions for architecture, statues etc because it was the 'ideal'. For us lot this means if you whack a rock a third of the way across the tank its meant to look more natural then if you put it in the middle.
All these 'rules' though wether Japanese or Greek were cultural things and observations so feel free to make your own observations too and not feel intimidated that you must do something that agrees with the 'principles of Iwagumi' or whatever.
My favourite tanks with rock formations normally ignore the rules to some degree for example this composition by Oliver Knott;

Centralised, no clear focal point (for me anyways) but it just works as it looks like something we would see in nature as a formation.
As for tank dimensions you can always use that as a limitation to fuel creativity as you then have some constraints to work with. My only setup is a nano that has unusual proportions but part of the fun was working how it would all fit in. My layout breaks the rules too as your meant to use odd numbers of rocks whilst I only have two obvious main rocks and four rocks in total. The main stone is positioned to roughly a third but then it sticks out above the waterline. Despite these things it agrees with my experience of nature and therefore looks 'right' to me.
By ignoring the rules to some degree you can create something unique to you.
