There are many icon themes available for Linux and you already know that in one icon set all icons have same pattern, but this is not the case here. The guy (0rax0) who designed this icon theme could have tested every shape on the planet to get a unique and good looking icon set for Linux, and he followed totally unshaped pattern for his icon set but can't we see these icons still looks awesome, I would say great contribution to eyecandy for the Linux. We all have tested many of the icon theme and none of them have icons for every application, there is always something missing, so don't expect this set to be complete but good news is that it is in development mode by another guy (ZMA) who is now constantly working on it and adding icons to this icon set. If you encounter any issue or see any missing icon then you should ask ZMA to create and add that icon. You can use Unity Tweak Tool, Gnome-tweak-tool to change themes/icons.
