Yes; this one took around 3 minutes too, David. Used the default custom formula. If you use just z it still would take 3 minutes; of course no change happens afterwards with just z. Still nice to see this ability; maybe can be speed up some. :)

I'm assuming you need to use the pre release gmic to get that filter?

Yes, Sallyanne, you do need the Gmic 2 but you can install both. They live quite happily together on my machine.

Great turing, Lyle, but very hard on the eyes.

I'm a bit worried about the timings you get.
Could someone try the filter on Linux. Even on my laptop, it takes like 8 seconds for a 3000x3000 color image, so I can't understand why it should take 3x60 = 180 seconds on another machine, even on Windows ! There must be something wrong that should be fixed.

Thanks James, how many available cores do you have for the computation ?

EDIT : I've always found that gmic on Windows was a bit slower than on Linux, without any explanations why it is like this. Maybe there's only a simple hack to perform to get the same performance as in Linux, I'd be happy to know :)

Yes, Lyle, that would help, really :)
If you find that it is way faster, even on a VM, then we can worry a bit much about the Windows version !
