gkII was initially based upon Osku Salerma's gfract.
gkII can use one of five secondary equations in partnership with the equation for calculating Mandelbrot images. These secondary equations are known within gkII as Kunge and have the effect of hiding and warping the Mandelbrot set. The effect ranges from very subtle to complete annihilation, depending where you zoom. In the way you can accumulate features of the Mandelbrot by zooming into them, so you can with the kunge types also.
After almost two years a new release of gkII has sidled out from the darkness back onto the modern desktop! Yes, gkII now will build with recent releases of GTK2. The new release is primarily a bug fix release - gkII had been suffering for too long with code which had been deprecated by GTK2. gkII now builds against gtk+-2.18.3 no problem - even when errors are forced upon encountering deprecated deprecated code. As you can tell, I'm quite pleased about this. That's it, that's all there is to it.
I guess at this stage I should point out IT IS A LINUX program which will not work in Windows.
( + indicates feature gfract does not have. % indicates different implimentation of shared feature. )
* Any image size (on provision of enough memory for it)
* Uses the "long double" data type for calculation giving greater depth of zoom than some other software.
* Image antialising
* Colour interpolation and colour palette scaling
* 9 different Kunge types for mangling the M-Set (+)(four added in latest release)
* Real and imaginary perturbation (+)
* User definable colouring techniques (%)
* Automatically layer same fractal with different bailout values and/or perturbations. (+)
* Save image parameters.(+)
* toggle to zoom-in into a new window. (+)
* repositioning and image centering.(+)
* random colour palette generation and striping (+)
* Swap or Invert RGB colour channels in palette (+)
* No more mandatory run-time dependancies on colour palettes (+)
* * * NEW * * *
Now on jwm-art.net is a gallery of 40 straight-laced Mandelbrot Set images.
Broadband users should follow the link to Mandelbrot Exploration where the images are presented in the high quality PNG image file format at a 900 x 650 pixel size.
Dial-Up users should follow the link to Mandelbrot Exploration where the images are scaled down to 788 x 568 pixels and are presented in the lesser quality but far smaller JPEG image file format.
Take a look at these gkII-0.4.5 screenshots.
* Colour maps are now optional, but available from the gfract home page. Or if you have Fractint colour maps, use them.
Please choose the latest source release.

Build instructions are supplied with the source code, in INSTALL.
However, since gkII-0.4.6 needs a patch, here's some instruction:
1) Download gkII-src-0.4.6 and extract (
tar -jxf gkII-src-0.4.6)
2) Download gkII-src-0.4.6_afx_fix.patch and copy into the gkII-0.4.6 directory.
cd gkII-src-0.4.6; patch -p0 < gkII-src-0.4.6_afx_fix.patch
The file README supplied with the source code provides a brief guide on using gkII.
There is an assortment of gk2 files in the gallery directory within the source package.
If you have any questions concerning gkII, I'll be happy to assist. Please use this jwm-art.net contact form.
Slightly Technical information about the kunge equations if you're interested.
