] Visualizing huge numbers can be very difficult. People
] regularly talk about millions of miles, billions of
] bytes, or trillions of dollars, yet it's still hard to
] grasp just how much a "billion" really is. The MegaPenny
] Project aims to help by taking one small everyday item,
] the U.S. penny, and building on that to answer the
] question: "What would a billion (or a trillion) pennies
] look like?"
