Incan Binary? via /.

...If Professor Urton is right, it means the Inca not only invented a form of binary code more than 500 years before the invention of the computer, but they used it as part of the only three-dimensional written language. "They could have used it to represent a lot of information," he says. "Each element could have been a name, an identity or an activity as part of telling a story or a myth. It had considerable flexibility. I think a skilled khipu-keeper would have recognised the language. They would have looked and felt and used their store of knowledge in much the way we do when reading words."

There is also some anecdotal evidence that khipu were more than mere knots on a string used for storing calculations. The Spanish recorded capturing one Inca native trying to conceal a khipu which, he said, recorded everything done in his homeland "both the good and the evil". Unfortunately, in this as in many other encounters, the Spanish burnt the khipu and punished the native for having it, a typical response that did not engender an understanding of how the Inca used their khipu.
