I came across this when I was downloading some other stuff off of a site. It is an entirely novel way of doing text entry where you never take the stylus off of the screen but rather use a series of continuous line movements to input text. It was originally developed by a computer scientist at NYU and he submitted an academic paper where he stated it was up to 3X faster than graffiti once the user had spent a few hours working with it. It definitely has a *much* steeper learning curve than graffiti, but since I haven't had much luck with the other input methods on my Axim I figured I would give it a shot (not ever having owned a palm I am not graffiti literate).
After just a few minutes of use I can find myself getting into the flow and that it will be a fairly fast input system. I won't be writing War and Peace with it, but heck, that is what my PocketOp is for...
Here is a link to the original (I like this one better). They also have a "game" to help you hone your ability:

Here is another take on the same concept (I tried this one first):
