What is the Obama's Logo？

I talked with one of my friends a moment ago.
I said, "You should change, you can have a better life."
He said, "I am waiting for the big change, I should stare at it silently.What is the Obama's Logo?"

I said in my heart, "It's hope, the rising sun, the circle of life, the circle of change."
用中国话讲以上叫“故弄玄虚”，不就是几千年前就有的八卦图里的道理么，只可惜现在越来越少中国年轻人关注中国文化了。老外用了也不引用，谴责之！
