I found out this usefull class after searching for a bit, so I thought to let you all know about its existence :) couldnt get normal means to work well so.. here's anyway a quote from the .h:

CODE

// This C++ code uses the simple, very fast "KISS" (Keep It Simple
// Stupid) random number generator suggested by George Marsaglia in a
// Usenet posting from 1999. He describes it as "one of my favorite
// generators". It generates high-quality random numbers that
// apparently pass all commonly used tests for randomness. In fact, it
// generates random numbers by combining the results of three other good
// random number generators that have different periods and are
// constructed from completely different algorithms. It does not have
// the ultra-long period of some other generators - a "problem" that can
// be fixed fairly easily - but that seems to be its only potential
// problem. The period is about 2^123.

I had to make a bit of tweaking to make it compile on my university's g++ compiler which enforces pretty strict rules for ANSI-C++ and such things, for those who are interested.. the modified .h is available here (just removed the static consts and initiated the double's in the constructor):

(I'm not sure if I should put this to news instead, this isnt really a support request but rather sharing a solution to something)
