Almost of people had or have their own dreams.
Some of them come true and are sometimes forgotten as time goes by.
I described one's dreaming in the past, present or future with the saw-toothed wheels image.
In addition I chose diverse ranged colours based on the rainbow and standarized them to the bright tone considering the target, children in the world.
At last, I hope anyone not to give up their dreams easily, because they are worth it above the gold.
