A New Desktop Design - 8ball-media

v0.2 of my new desktop design made with GeekTool

During the rainy weekend i spent some time to fiddle around a bit with the “geektool”.
After researching a bit about shell programming and reviewing a lot of scripts and examples i wrote some for myself.

With a good looking wallpaper and the script collection in place this is the result (for now).

Note: credits for the wallpaper found on deviantart.com
