This reminded me of something I saw at the Science Museum in London a few years ago.

A round clock face is used to represent the history of the earth and a narrator tells us the geological events that happen as the clock hands travels around the clock face. At a few seconds to midnight, we're told this is when humans appear.

I thought it was a clever way of illustrating how human history occupies such a tiny segment in the overall scale of the earth's history. (I don't know if the exhibit is still there)
