i dont think that rom has many themes out yet...maybe one or two...its still a fairly new rom..i always look for any new themes cuz i liked that rom so unless there are more somewhere i dont know about lol.......i know there are some skins and mods you can put on it, but thats about it
anything out for the evolved rom should be right here on XDA....
im sure there will be more when the rom is released as RLS....if you interested in the themeing, Kings Roms have lots of themes for them...the only problem is that some of the Kings Roms are fairly big and if you use a lot of apps, you should partition your sd
In theory, any theme made for Mik3D should work for evolved ROM because they are the same base. Key word is "should". Obviously make a nandroid before you try this, and dribble some fresh chicken blood over some randomly scattered bones.
If it works post about it, if it doesn't absolutely post about it and warn others.
