This is a fun script to work with. You can get it here.

I made chocolate drops with it and used dd's bevel script and color curves on the results, then I made a brush with them.

The script is here in GIMP: <Image> Filters > SambrookJM > Grid - Circular...

Has Sam added the different sized circles in each layer option yet? :)
Nice drops there O!

They look like wooden backgammon chips to me though.dds script works nicely on them too.

Rod: I checked the script and the answer is no, he hasn't updated it yet. I'm fairly certain he'll post an update when he does. I wanted to leave a "Reminder" post, but decided it might be irritating to do that. :)

O: Nice beveled textured circles!

Interesting idea. I have to play with it a little bit, and see what I can use it for.

I always save a xcf and then save a copy as png or jpg, depending on my mood at the time. :proppeng

Mahvin another excellent addition to the script would be if it had a option to use octagons, hex, square, or diamonds.
I wonder if those shape options would be easy to add to it ourselves.
Then you could make some killer interfaces for music players and what not. :)

I'll leave the selection option to you, but here are the calcs:

replace:
(gimp-ellipse-select theImage xStart yStart circDiam circDiam CHANNEL-OP-REPLACE FALSE FALSE 0)


for squares:
(gimp-rect-select theImage xStart yStart circDiam circDiam CHANNEL-OP-REPLACE FALSE 0)


for diamonds:
(gimp-free-select theImage 8
  (vector
    xStart (+ yStart (* circDiam 0.5))
    (+ xStart (* circDiam 0.5)) yStart
    (+ xStart circDiam) (+ yStart (* circDiam 0.5))
    (+ xStart (* circDiam 0.5)) (+ yStart circDiam)
  )
  CHANNEL-OP-REPLACE TRUE FALSE 0)


for hexs:
(gimp-free-select theImage 12
   (vector xStart (+ yStart (* circDiam 0.5))
     (+ xStart (* circDiam 0.25)) (+ yStart (* circDiam 0.067))
     (+ xStart (* circDiam 0.75)) (+ yStart (* circDiam 0.067))
     (+ xStart circDiam) (+ yStart (* circDiam 0.5))
     (+ xStart (* circDiam 0.75)) (+ yStart (* circDiam 0.933))
     (+ xStart (* circDiam 0.25)) (+ yStart (* circDiam 0.933))
  )
  CHANNEL-OP-REPLACE TRUE FALSE 0)


for octagons:
(gimp-free-select theImage 16
  (vector (+ xStart (* circDiam 0.2929)) yStart
    (+ xStart (* circDiam 0.7071)) yStart
    (+ xStart circDiam) (+ yStart (* circDiam 0.2929))
    (+ xStart circDiam) (+ yStart (* circDiam 0.7071))
    (+ xStart (* circDiam 0.7071)) (+ yStart circDiam)
    (+ xStart (* circDiam 0.2929)) (+ yStart circDiam)
    xStart (+ yStart (* circDiam 0.7071))
    xStart (+ yStart (* circDiam 0.2929))
  )
  CHANNEL-OP-REPLACE TRUE FALSE 0)


(all tested)

Looks cool; also could use G'MIC Polkadots preset to get similar results. Adaptive Voronoi would be cool, but so far no one's taken this challenge so I have to use a command line stand-a-lone (Secord's ImageMagicK program is now broken) to do that. :)
