Hi Pilou,

thanks, but i think it is not in there and to answer your
question, no it is not a Reaction Diffusion pattern.

@PaQ in case you are still following this thread, can
you archive also an importable and smooth noise
pattern into MoI, like you have shown, when using
the Unified Noise examples 8 and 14?

www.sidefx.com/docs/houdini/nodes/vop/unifiednoise.html

If so then i think we all would very much appreciate how to
archive such a result, because if you look closely at the shown
examples they both are spikey in some areas too.

Regards
Stefan
