  The ISAAC RNG is faster than MT. I don't know about quality, but it should
be very competitive at least.

  One of the basic things taught at school is that you should never attempt
to make your own PRNG if you don't have extensive experience about the
subject, if you want any kind of quality to it.

  Another thing with the exact same rule is a hashing function.
