New to Typophile? Accounts are free, and easy to set up.
It is a script I wrote to create and size object within an illustrator document in the ratio of the golden section.
It will work under os X on a Mac with illustrator and applescript active.
prior to running the script you need to install the ScriptingAdditions from Satimage, in their readme file they tell you where to place the additions.
Inside the script there is different value that will let you modify the polygone shape.
Every time you hit run there is one new polygone created in the sequence.
Hope it will be usefull.
