Ok, this was my attempt to create the same effect entirely in G'MIC, and I couldn't do it completely, due to bump mapping.
However, this image was done using strictly G'MIC up to the point of bump mapping:
1. Ran turbulence (found in Rendering - for the GIMP noobs) - btw, where I come from, being called a noob is a term of endearment, not an insult, just so you know...). Settings here don't matter, because you're out to pick your own color scheme.
2. Additive noise (under Degradations) - set at 20 (Gaussian)
3. Ran Stained Glass filter (found in Patterns) as indicated before (but this time, it wouldn't let me set the edge slider past 40 before going to a black screen - so 40'ish is the max on edges, use .05 shading - the rest at default). Now select OK and then duplicate the resulting layer so you have two copies.
4. Run the top copy under Morphological filter (under Contours) I used size 6 and octagonal shape, rest at default settings. Select OK.
At this point, I had to rely on GIMP to prep for bump mapping, I didn't see any G'MIC equivalents, although in one instance, after running Morphological filter, I fiddled around with Gradient norm in Contours in so many different ways and ended up with shiny metal foil looking tiles (too many settings to recall which were which, but it still didn't give me the tile/grout look I was actually after). If you want shiny metal foil or color hard candy looking tiles, you can obtain that using various Gradient norm settings in Contours. However, this is more about tile and grout, so on to step...
5. Using the Color Select tool, click the black line anywhere on the image to select it. Copy the selection and paste as new layer. (This was what I was hoping Gradient norm would do in G'MIC, to eliminate the next few steps).
6. Add a new white layer under the black line, and merge the black line layer down.
7. Gaussian blur of the new black line layer at 6-8 px. Run Colors - Curves. The idea is to have a good line blend for bump map, not too dark, not too thick, not too thin...
8. I inverted my line curve result then set the layer mode to addition (screen or difference will work, too).
9. Select the mosaic layer, and bump map using the top inverted layer. I used ambient to lighten up the dark areas (I encourage people finding their own bump map settings). Just remember, if it turns out too dark, use the Ambient slider to lighten it up. Then blur the mosaic layer at about 4 px.
Sure would be nice if you could perform ALL these tasks in one lovely little filter called Tile Maker.
