The MegaPenny Project

We hear the word billion used on a regular basis these days, yet, how well do we really comprehend the scale of such a large number?

Using a simple standard U.S. one-cent coin, the MegaPenny Project has produced a very cool visual guaranteed to help anyone gain perspective on such large numbers as well as exponential growth. They start out with one penny and work their way up to one quintillion pennies.

I noticed that they’ve recently added a new special bonus section called MegaMoo that stacks up large numbers of cows.

Incidentally, the U.S. penny and the Canadian penny are both 19.05 mm in diameter, however, the Canadian coin is slightly thinner.
