>Amazingly, it even renders stock charts, something the blind have never had access to. Sold.

Can someone explain this to me? How can a chart be "rendered" for a blind person?

You move your finger over the stock chart, and it reads out the X and Y values to you. Eg: "May 28 10, 256.17" (i.e, on May 28 2010, the stock was trading at $256.17). You can scan the chart with your finger to get the whole thing described.
