interesting things to do with java moss?

Well, it was worth a shot. :) I've also seen some pretty awesome moss "clouds" that look cool. Not sure how you'd go about doing that though.
 
just type in 'java moss tree' or something like that on google image. there's a bunch of images of moss trees but a lot of the tanks seem to need co2 for the moss/plants to grow nice.
