Very first build of Swami is in the repo along with a base attempt at a theme selection module. It applies the selected Moksha theme and attempts to apply a matching elementary theme with the exact same name.
Works OK in my limited testing here, almost 2am though so take that with a grain of salt - heading to sleep.
You can install / keep up to date with my work on Swami by installing the pre-release package:
sudo apt-get install swami-control
Note because this is a pre-release I'm going to be pushing updates for it directly into the main repo. Anyone on a non-Bodhi OS who would like to give Swami a try can find the source code on github here.
