Title: Off-axis vortex ring collisions

Description: Vortex rings are propelled towards each other at varying impact parameters.
Different behaviors can be observed as the impact parameter is changed. At small impact parameters, rings expand and rotate due to the collision. As impact parameter increases, rings pass by each other, producing instability and breakdown into turbulence.
