This filter "quantizes" an image (the user chooses the number of colours) then fills each separated colour area with a gradient chosen randomly from a set (the user enters a "discriminant" text, used by Gimp to extract the subset of gradients wanted).
The filter by default makes use of the discriminant "mandelbulb_" which determines the extraction of all gradients of the Mandelbul_nnn set present in the user's active gradients.
If you do not have it and you want to try my preferred set for this filter, I attach it below.
Here the filter:

Here my gradients set: (I have many others)

Here an example of outcome:


Please remember: each gradient used is selected randomly, hence practically you will almost never get the same outcome you already got

hello dinasset
Is it the same as "DIEGO_DRAWING_Experimenting P"?

Now that's what I call acid wash artwork. I like what I'm seeing, Diego.

Yes, it's the official release of it.

I didn't know that term "acid wash artwork". Thanks for your "like".

Thank you dinasset.

Found this image on Google as "acid wash artwork" (hope I do not violate copyright, I didn't find info about this piece)

Thanks dinasset. I did an experiment with Experiment P.

lololol

Your search found a render that I did a few years back, Diego; link to flickr below.
