srand value
Well, I tried but I’m not sure what value has to be (in what range), it seems still to be random though.
Thank you.
Would it be possible to record coordinates of particles or seed points then interpolate between the instances to animate? Sorry that this is a word-salad; just trying to brainstorm.

Everything is possible with a bit of time and motivation 
I think my experiments are over for this episode of G’MIC Adventures, but if someone wants to experiment new things related to it, that would be awesome!

…modulate the trail map by a grey scale image

How did you do that? I guess the filter alone is enough? Haven’t tried it yet.
i’m not proficient in g’mic, so i used the glsl source code from the interactive physarium github. the only change is that i input another image and multiply it to the trail map directly after the blur step. this must be a one-liner change in g’mic
