Darn he beat me to it (the moss tree). Well, there's a lot of things you can do with moss; the only thing that's stopping you is your imagination. I've seen a scape somewhere where someone used it as flames on a building (the building was just a decor). Thought that was pretty cool. Then someone tried to make christmas tree with, of all the mosses, christmas moss and toothpicks. Would probably work just as well with small branches. Anyways, let your imagination run wild and have fun scaping!
