Pretty simple theme. Has a semi-transparent Title and Tab bar. Green theme. Custom Icons and such. Used default theme as the base so hopefully you wont have any problems installing. Enjoy!
If you do have problems installing from the "Install Skin" prompt extract the 154180-allYakedUp.tar.gz, then with sudo cp the "allYakedup" directory to /usr/share/kde4/apps/yakuake/skins/ and then go in and select the theme
