Agreed. I watched a guy doing that & he did sell some, but couldn't have been making more than a couple of bucks an hour. The process was very impressive to watch, but the end result, as art, was really lacking. A case of the whole being less than a sum of its parts.
I think it's the same as with epoxy river tables & fractal burning. Like wow, look what we can do here. But after the new wears off it just ain't that great.
