Un très très très bon plug-in!!! "Artistic --> Rodilius" = Fractalius \o/ Un must-have!
With the GIMP plugin the fourier transform (inverse) comes up with lots of "Command 'normalize' : Invalid argument" error messages; libfftw3-3.dll seems out of date. Pity.
I really enjoy using G'MIC and use it's features inside of Gimp before using any other plug-in's features. I often restore old scanned film photographs, negatives, and slides and its capabilities keep me confident in being able to restore even the most challenging materials. I scored it a 4 on support only because I haven't ever needed to use their support and can't really rate it.
