I have an idea, but I'm not capable of bringing it to fruition as I just don't have the skills. I'll explain it as short and sweet as I can and if someone with the skills wants to take a shot at it, please do.
I'm picturing a persons head( could be multiple heads) done in a minimalistic style, like the pictures you often see of faces that only use a few lines, but still make a good representation of the face. The face(s) would be blowing out vapor at a slighty upward angle almost straight forward, maybe a little bit off angle one way or the other. The vapor would culminate, partially obscuring the face(s) in locked vapor rings, Olympic ring style. Just an idea, I'd do it myself if I had the capability.
