Weather mod particle manipulation code snippets

//To make custom particles see this badly colored tutorial: http://coros.us/mods/wiki-modding?a=Custom_Particle_Textures

//spawning the leafs is just a matter of scanning around the player and looking for leaf blocks then spawning them like in the tutorial, not too complicated

//As for the more complicated manipulation of the particles....
