Imagine an abacus. Now imagine that abacus to be very large, as large as the side of a building, with hundreds of rows, each row with 256 possible arrangements.

Now imagine making different arrangements of the rows in that abacus, such that they are directions on how to change the arrangements of other rows in that same abacus. Further, suppose that this abacus can follow a series of these directions itself, without a person needing to do it.

What I do is to write a series of these instructions in order to accomplish specific tasks on the rest of the abacus. Adding numbers together, search through rows to find specific numbers, copying them. Numbers might represent points on a map, accounts in a business, words in a book, even colors in a picture, like you might find in a tapestry.

But then imagine this abacus is the size of a whole city - that's the number of rows it has. But its elements are so small that the whole of it can fit in your pocket. And it uses the same energy to accomplish its tasks that is found in a bolt of lightning, but in very small amounts.
