oh yes, those brycean fractals are certainly of a different nature then the ones used in apophysis, ultimate fractal or other fractal porograms. I don't know about apophysis, but Ultimate Fractal lets you generate your own fractals mathematically and they are really rather hard to make, even if they are, in a way, more simple (and very different) then the ones used in bryce. To allow more freedom to make new procedurals DAZ could ofcourse have a look at Mojoworld, which allows you to combine and transform different base noises in as many ways as you could possibly want before even throwing them into any sort of fractal. Bryce lacks the flexibility in tweaking or combining base functions that Mojoworld has, however this could have to do with the fact that not all of bryce's procedurals make perfect mathematical sense (there's a lotta mathematical 'nonsense' in there apparently).
