Hi, A friend of mine has been working on a radioactive RNG and while playing with it a potentialy interesting application came to mind. In short, by placing radioactive RNG's in some sort of grid across an area it becomes possible to track radioactive sources by comparing the magnitude of a correlation function between them. This could be extended to include just about any kind of RNG that is sensitive to some environmental factor, say air pressure or magnetic intensity... ____________________________________________________________________ | | | The financial policy of the welfare state requires that there | | be no way for the owners of wealth to protect themselves. | | | | -Alan Greenspan- | | | | _____ The Armadillo Group | | ,::////;::-.
