Also, I want to add that I really dig the non-traditional edgespots and the clean look of the current design. It’s terrific.
With that said, one complaint I see often is that we don’t take full advantage of the ceramic medium when we mimic clay edgespots. I’m only guessing, but I think it’s possible to take these chips to another level with an even more unorthodox look.
I am definitely not an artist and couldn’t have come close to what you’ve already created, which again is magnificent, so please don’t take the above as criticism. It’s just something to consider. If it’s of interest, perhaps you could draw inspiration from using google images and searching dune theme, original dune book covers, house atreides/harkonen/corrino/etc sigil, crysknife, etc.
And one last thing, one of my favorite factions in Dune is the Bene Gesserit, who caught the men of destiny in their web. I wonder if there’s something more that can be done with this notion and the web mold. (The Bene Gesserit sigil unfortunately doesn’t really match the web mold, at least to my pedestrian eye)
