[Watchmen] why does Rorschachs mask move like it does?

I saw a video on the news of Rorschach and his masked looked like it was moving is there any reason behind this does anyone know?

The mask has an outside layer, which is transparent, and an inside layer. Between the layers are two fluids, one black, one white, and about as thick as oil. The fluids are of a type that they never mix, and body heat/movement keeps them in motion. The design of the mask keeps the shapes made symmetrical down the center (I have no idea how that part works)
