So for a Friday I thought I would release my Black-Transparent Plasma and bespin themes together in the zip file. This is my first attempt at making a plasma theme other than for myself so it may not work right for you.
It's actually a few themes mixed together so credit goes to the authors of the following for creating awesome work Air, Caledonia [link]
and Ronak by the Chakra-Project [link]
and the bespin is just Cupertino.100a that is included in the svn of bespin that I re-colored black and made it transparent.
Instructions extract it and move the black-transparent.bespin out and into your home folder and copy the plasma theme to your .kde or .kde4/share/apps/desktopthemes
To use the bespin just open up the bespin config and go to presets then import it.
Enjoy and have a great weekend!
