Any other Zelda fans here? How about an Ocarina plug-in that lets you play songs (by pressing the correct keys) to change the time of day and weather? Probably would have to be a client mod too though =/ Shouldn't be too hard to make. =D
I released a plugin exactly like this a couple days ago, then decided to search it afterwards and found this... http://dev.bukkit.org/server-mods/ocarinasong/ If anyone's still interested. Server plugin, doesn't require spout.. Was thinking about making a (better) spout version, but first I've got to finish this one.
