Exercise 6c Concept of Hierarchy

Given:

A minimum number of 67 2D elements which shuold include square,rectangle and isosceles right triangles.
The smallest unit of the measuring system should be 2,5 cm
Design should occupy a volume of approximately 27000cm3


After and big fat FD I understood what I wasn't suppose to do more. Main idea here is a single initial group is rotating while in every rotation gradually extending It's number of elements.
We were asked improve the model later and here it is the improved version.
