Visualizing Enormous Numbers

Here are two sites that help us to visualize really big numbers.

The first one is called the MegaPenny Project:

It's aim is just to show how many of a number looks like, and they chose pennies.

The second one is called "What does one TRILLION dollars look like?" And it shows you what it would look like if you had that much in cash.
