This is a modified version of Ubuntu\'s default Ambiance and Radiance themes, made to more closely resemble the interface from Ubuntu Touch.
This is based on Ubuntu\'s light-themes package (https://launchpad.net/light-themes).
For the Touch-style launcher icons, see this WebUpd8 article: http://www.webupd8.org/2013/04/get-ubuntu-touch-feeling-on-unity.html
This theme is based on both the Ubuntu Touch look and this mockup by Lucas Romero Di Benedetto: https://plus.google.com/104438618743851678614/posts/WL5iugZPnXd
*** INSTALLATION INSTRUCTIONS ***
To install these themes on your system, extract the tarball and copy the Ambiance and Radiance folders to ~/.themes/. Then use a tool like Unity Tweak Tool (http://apt.ubuntu.com/p/unity-tweak-tool)to select one of them as your theme. (I think this overrides the default themes as long as they're installed. You may have to log out and in again to see changes.)
