How to draw a picture of God creating man in his image. Any ideas?

This might be difficult. That God created man in His own image does not mean physical image. Does God have a physical image?

Think about what "in His image" means. Consider that man may have been created to be a thinking, conscious being with the ability to discern right from wrong. He may have been endowed with the ability to learn, to feel empathy.

Recently I heard that Michelangelo's painting on the ceiling of the Sistine Chapel may be the greatest representation of what you are seeking to render, rather part of the painting is. In this rendering, Adam is reaching out to God with a pointed finger, and God is pointing back. That act, pointing defines the primary difference between man and all other animals. No other animal is actually capable of pointing. Think about it.
