You can access the latest TintedGlass theme via git. There are currently four branches you can choose from.
The 0.24 branch is of course for MythTV version 0.24.
The experimental branch based of the master branch contains modifications that may or may not make it into a released version.
The master branch is for trunk. ( currently 0.25 ).
The mythtv-master branch is used by the MythTV developers for the built
in theme chooser. It may be behind the master branch at times.
You can clone the repo:
git clone git://github.com/hpeters/TintedGlass.git
Or you can follow the link above MythTV-Theme-Git-Access and download snapshots of the branches.
I will also continue to create tar bz2 files as well.
