#ParticleWorld
ParticleWorld is actually two classes: particle and world. Particle is a single particle, world is a collection of particles.
Both classes are dependent on math and vector3dm (my own vector class found in another repo).
What I expect is that these will be used as base classes for more sophisticated systems. But out of the box, world will create a bunch of random particles and cause them to fall according to gravity while displaying them.
I've added my own extended class: pixie world. It is, in turn, two classes: Pixie which is a single pixie and world which is a collection of pixies. I added one pixie which tries to fly toward a series of goals. It flits around until you hit esc.
Love to see what you build with this!
