This particle system is fully customisable so can be set to emit any graphic. It uses a “dummy” in the way you might if you were using a 3D program. This dummy can then be animated (in this case along a path) and the particles will be emitted from that point.
There is a small amount of code, none of which you really need to understand. Most of the work happens in the Stardust class, meaning all you have to do is play with a few variables until you get the effect you are looking for!
