Since this is now a new GUI specific forum I would just like to state the following:

All SS themes which are still in development are now available for 10.2.3. All are refined as well. NeXT is the only theme I still need to update and release. Both of the Power themes are no longer in development due to my strong distaste for them.
Screenies:

SS ChosenOS


SimpleX


Pearl


Cappuccino


BeOSX


NeXT
