If you wanted to somehow illustrate the complex vorticular dynamics of the dual Torus structure that defines black holes on all scales all in one simple 2-dimensional symbol, you might draw something similar to the ancient Chinese Yin and Yang symbol.
This animation, which was created by animators directed by Nassim Haramein for his "Black Whole" DVD, shows how the dual torus and the Yin Yang are describing the very same dynamics through animated graphics.
