Creating a branding system is always a intricate process, it requires a lot of thinking especially on how to make things look as they are part of a family, sometimes some varitions look better than the other but the overall look and feel should remain familiar. The work that Andrea Alati and Simone Mariano is a great example. The project is titled HITALK - Dynamic Brand Identity and it's awesome to see how they play with the isometric grid and the different variations of style and colors.
