How much is 1.5 trillion dollars?

Keep in mind, the US is in debt by 12-13 trillion dollars and counting. Lets round up and say we are headed for 15 trillion. Look at the image below or Click on this link to see a more detailed picture of quantifying 1.5 trillion dollars. Now assume 1 PIXEL is 10 million, then the larger picture is 15 trillion. I would love to see the same picture with a pixel being 10,000 dollars, a number more comprehensible to an average person.

Once you go over a billion, people including me cannot understand trillions, but a picture helps.
Thanks to Lomba for the image.
