Yea, I seen that yesterday, I downloaded the video tutorial. I always wondered how they did that. I went over the tutorial rather quickly, but I did notice, you import the theme using python scripts.
They even have a theme repository. You can download them and, import them into your user preference panel.
Theme Repository:

There are a lot of good tutorials on that search.
I found a tutorial on, advance animation. Lip-Sync with Shape Keys. It's intense, but I managed to set the basic shape key, and the 1st shape key.
I've seen some samples on YouTube, that some folks did in Blender. Cool!

I still can't seem to find anything on Linux desktop panels, and Blender.

There is a lot of stuff on the user preference panel.
