Well, what I meant by Bryce-like... you've got stucco, fractal, 
multifractal (really I think these are just variations on perlin), grid, 
sine (both boring), random paths, marble, voroni... and some others that 
the names aren't really meaningful.

What would also be a powerful addition is the ability to control 
frequency/density/scaling in a non-uniform manner, to add octaves in one 
pass (i.e. without doing it by hand by running the filter several 
times), and to apply a linear filter the noise function before color 
mapping (all things Bryce does). Bryce also does rotation and "phase" 
(using a second noise generator to jitter the coordinates of the first).

D'oh, that *does* look like PS's "Clouds" filter :-). How configurable 
is it currently? (Apparently my Krita doesn't have it, either :-(, must 
be missing the plugin pack or something.)
