All pictures (klines/*.jpg) are rendered with Povray 3.0 and manipulated with ImageMagick. Povray & bash scripts are in the directory >klines/povray. Customise balls.pov as you want, render and install it.
You need Povray 3.0 to render. In newer Versions i.e. 3.1 “halo” is supressed.
In order to generate marbles on your system, type the following in the base directory of the kdegames distribution:
% cd klines % make install
