Amazingly, you can create Guilloche patterns in GIMP fairly easily.

That pattern looks pretty good.

Interestingly enough another filter just came out on the registry called gat-lines

You can get some neat results after running it with both directions and a little iwarp action with the Swirl selection tool.

There are several other interesting:

Sinedots II (8bf)

Winplot for Windows 95/98/ME/2K/XP/Vista/7 (802K)

Peanut Software Homepage

Winplot is not a plugin for Gimp - but with export: eps, svg ...
Dream slowly - if something similar would be in G'MIC ...

I saw that and couldn't figure what it gave beyond the built-in Filters->Render->Patterns->Grid and just setting one grid to 0?

I just checked my first post and can't believe I didn't add the "how I did it" part.

I used script-fu-shapes.scm from the Registry:

http://registry.gimp.org/node/22016

This script needs to be fixed, though, it won't allow you to use any other placement of x and y on your image, only "auto center". So be warned, if you turn off auto center, the script will crash. I've sent the author an email LONG time ago, and again yesterday. As long as you use auto center, it works fine. Maybe Saulgoode or RobA would want to take a look at it, to see why it's not working when "auto center" is off?

I tried using that script a couple of months ago and it has more problems than just "auto-center".

So, as an exercise to learn Script-Fu, I rewrote it, keeping only the part for paths. (I've never used a LISP family language before.)

The script registers in the paths menu (right-click on a path) as Copy-rotate-shift...

This one does allow you to use any brush tip.I do not know if the grid tool does or not.I still do not know what you would use GAT for though :lol

It was an experiment in running plug-ins with a choice of language also.A language file is included in the setup.
