For situations where you have a fire particle emitter and you want to have light produced not just at the source of the fire, but also ever-decreasing amounts of light in a trail as the heat source moves around (so you have a trail of fire that dissipates after a half-second, etc.)

You could spawn lights after a mouse movement threshold is met and have each light die out over a short period of time. In other words, if the mouse hasn’t moved don’t spawn any lights, but if it has, then spawn a new light every x distance. Allows you have to a couple of lights dynamically created/killed as the heat source moves around.
