This is Brahma, the alleged creator of the universe. He’s supposed to have 4 heads, each having mastery over one of the four vedas. Traditional depictions are with four separate heads but I felt I had to do something different to show this, hence my attempt at making it a more geometric representation with a head facing each direction.
I fact, I was so fascinated by how this looked that I promptly made the head my avatar on multiple sites :-)
