The Inheritance Effector is probably one of the most underrated and underutilized effectors in the effector menu.  In part two of my Inheritance Effector tutorial, I show you how you can fake particle movement that would normally only be able to be achieved with an Emitter or Thinking Particles and Xpresso.  Using a combination of the Inheritance Effector and other Mograph Effectors and Deformers, you can achieve close to the same effect as an Emitter or Thinking Particles as a simpler alternative in your normal workflow without having to touch Xpresso.
