"Thinking about it"
original art & motion by Werner Hornung
If you have an apple and I have an apple and we exchange these apples then you and I will still each have one apple. But if you have an idea and I have an idea and we exchange these ideas, then each of us will have two ideas.
George Bernard Shaw
