Blur Particles adds a blur effect to the particles, which increases over the particle's life time.
It uses a custom vertex shader:

Start and Stop simply sets the running and paused states of a ParticleSystem. While the system does not perform any simulation when stopped or paused, a restart restarts the simulation from the beginning, while unpausing resumes the simulation from where it was.

+ Timed group changes is an example that highlights the ParticleGroup element. While normally referring to groups with a string name is sufficient, additional effects can be
done by setting properties on groups.
The first group has a variable duration on it, but always transitions to the second group.
