By professor Hwang's "Platonic stars on Geometric Tube design", he classified and explained several different types of expansions in geometric tube designs, that is, horizon expansion, vertical expansion and skewed expansion. Here tube means a hollow cylindrical shape which is made of elastic materials,such as plastic for polyframe.
We create a kind of sphere with triple layers by using above three different expansions and connectors.

Sphere anf Platonic five solids are important subjects in mathematics. A kind of Sphere can be made by using twelve regular pentagonal shapes and twenty regular hexagonal shapes with elasticity. Here we made a kind of sphere by triple layer of different types of expansions. The most inner part is made by using vertical expansion of geometric tube design, the middle part is made by horizontal expansion and the outer sphere frame is composed of skewed expansion and vertical expansions.

In 2014 Sochi winter Olympic game was held in Russia and Seoul ICM 2014 and Bridges 2014 will be held in Seoul, South Korea. Blending sport with culture and education, Olympism seeks to create a way of life based on the joy found in effort the educational value of good example ans respect for universal fundamental ethical principles. The goal of the Olympic movement is to contribute to building a peaceful and better world by educating youth through sport practiced without discrimination of any kind and in the Olympic spirit.
I think that Bridges is also similar to Olympic in several aspects.
So I made solid olympic flag which is composed of horizontal, vertical and skew expansioned sphere frames.
