the method from l'Ecuyer is already used in the texas instruments graphic calculators. But they don't seem to have patented it (I don't know how to check that).
Anyway I agree to have more RNGs which can be useful for statistics simulations or kryptography. And I would like to know how one can play with the bacteria ;-) :) I will tell him.

PS did anyone receive the mail that I sent yesterday about syllogisms?

But I wanted to know what you think.
Great !
Maybe better to integrate them in Sci-talk with the existing Random Number Generator (RNG). We have already 5 RNGs. I'm working on refactoring the RNG and distributions in Sci-Talk, because there is some redundancy until now: https://groups.google.com/forum/#!topic/scismalltalk/zXEyeGvTmJk <https://groups.google.com/forum/#%21topic/scismalltalk/zXEyeGvTmJk>
