OK, not sure about this ........ I would not, for instance post a MojoWorld image in the Fractal gallery, because, although the thing is based totally on fractals, the output is actually a landscape, not a fractal per se. Ditto for Terragen. However, there is no black & white compartmentalisation to this, because as you point out, nature IS fractals. A grain of sand, a rock, or a coastline - they're all fractal based, just at different levels. So do we say that the Fractal Gallery is only for fractals of a Julia / Mandelbrot / IFS nature? Probably not, because that would be unduly restrictive. Don't know the answer to this one - we could go round in circles for ever and not reach the end - which would be a very "fractally" sort of thing to do!!!! :-) Anyway, what's with all this "Bryce" stuff - everybody knows that Vue is the best 3D package around.....
