I'm working on something that will strip some of the
noise out of the positional data by possibly predicting
movement. does anyone know if there are any books/papers
that discuss a decent way of doing this without having
a lag most of the time?  My first goal is to make a game
of rock/paper/scissors (once I get vogle up and running).
Anyway, have fun with this code...
