designer's own words:'Class society' is a work for reconsideration of human descrimination and cruelmess to animals. I used light color and simplified shapes to give easy, comic, also ironic impression. The question 'what is your rank?' will make ourselves to look into our heart and try to face this invisible piramid in our lives. Eliminating this piramid of inequality is on the process of making true harmony of human and nature. That's the purpose of green design, also a duty of everyone dwelling on this planet. thank you.
