Accretion disks are the engines of the universe, fueling everything from newborn stars to supermassive black holes. While often modeled as simple, flat, circular rings, real disks are rarely so well-behaved. They are frequently born with misalignments or eccentricities and are prone to internal instabilities that break their symmetry. In this talk, I will explore the 'non-traditional' side of disk dynamics. We will discuss how magnetic fields influence spiral density waves in gravitationally unstable disks and how 'warped' disks can either generate internal turbulence or violently break apart. Finally, I will show why eccentric disks don't always circularize; instead, they can pile up highly eccentric flow at their inner edges. Their asymmetric structures offer a compelling new physical model for understanding the complex emission and variability we see in Active Galactic Nuclei (AGN).
