Just updated my original SONAR Platinum theme called "Mercury Light Green" (mostly Mercury with green highlights replacing the blue ones) to CbB.
It was a pretty quick pass through the theme and there may be some things I missed or did not get the shade just right. If so, let me know. The theme may be found on my google page along with the rest of my CbB stuff.
I will try to keep it current but since it is not my everyday theme there are no guarantees.
