Famed artist and sculptor Michelangelo left an array of easter eggs hidden in his works.
The Creation of Adam[]
The Creation of Adam is a panel in the Sistine Chapel, and perhaps one of the best-known odes to the Book of Genesis. In it, God is reaching out his hand to Adam from within what looks like a floating cloud.
When a human brain is overlaid on the picture, however, it becomes readily apparent that God, the cloud, and all the elements thereof, including his green sash, are parts of the organ. Michelangelo was well-known for his cadaver dissections and had extensive knowledge of this structure.
