Here's a nifty particle system I made. It hasn't been approved yet, since the spell moderators over at TheHive are lazy bastards:

To test it, just type "test" in-game (without the quotes). To open it with the World Editor, you need JassNewGenPack, but you can also simply open it like any other wc3 custom map (as a custom game in single player).

Actually, I posted this here because there really is nothing to moderate in this section, so I wanted a discussion to start
