Well be frustrated no more as the theme is now available to download!
From the deviantart page: -
Here is the alpha release of the Ubuntu Light Re-Imagined mockup that I’ve submitted a while ago. Please do note that this was made on whim. I just got the urge to make my mockup a reality. I haven’t fully tested it yet and some widgets may not look as they should.
Theme needs the Murrine and Aurora GTK Engines. For convinience, add the Elementary Desktop ppa to have the Elemetary-Nautilus, the current tweaks and optimizations on the Aurora engine.
