It gets biased, because of distance=sqrt(2) on the diamond stage is conflicting with distance=1 on square stage, meaning that diamonds have larger area of influence than the squares, so the result isn't perfectly random and has predictable patterns.

I.e. 45 degree lines are 1.4 times more likely 90-degree ones.

but perfect randomness and unpredictability are not even the point of this algorithm. in fact, the existence of such patterns might be a plus given its use in terrain generation: white noise wouldn't make for a realistic terrain, would it?

>>3 God loves diagonal mountains going at 45 degree angles.
