Emitter with particles that follow a static field defined by particles

• onclick: background particles stop
• as user holds mouse, particles emerge from mouseclicks
• the paths are preserved as the particles travel outward from mouse xy
• should look like fireworks or something where the particles follow the curvilinear space of the field
• this is pretty much a particle emitter where the particles follow and animate the line integral 7
