Well, since rand(seed(X)) is basically a linear function, all the randomness
would have to come 100% from the input. So there's no point in using it
really.

I even tried things like seed(X*1234567*pi), but even then it only repeats a
few numbers over and over again. Guess it's because a linear function of a
linear function is just another linear function...

But I can't.

There are many reasons. For example I want my particle system to be
frame-independent, so that the even the randomness of the particles is the
same independent on the frame-rate used. I also need it for the cyclic
animation feature where the whole calculation process is basically run
through several times, and where the random numbers must be the same each
time.

I have considered the array solution myself, but it would have to be a very
large array, and it would be a clumsy solution. :(
