Can you spot who is in this photograph? It looks like ex-President Bill Clinton, along with his Vice President, Al Gore. Clinton stands in the foreground, speaking into the microphone, while Gore stands behind.
Actually, the image is of Clinton and Clinton. Both faces are the ex President?s. The one behind features the dark hair and suit of Al Gore. We think it is Al Gore because of our familiarity with his appearance, and the fact that he was always with Clinton.
This type of illusion is known as a facial illusion and it uses photographs that have been altered.
Looks like Ex-President Bill Clinton
and his Vice President Al Gore, right?
Wrong... It's Clinton's face twice, with two different haircuts.
