I think you didn't read the post to well.
Like he said, water is dripping on a nearby branch.
That, and that i mentioned moss growing spontaeneously on organic decoration ;-)

I've built some waterfeatures myself using epoxy raisin i pressed tree fern dust in,
moss appeared after about 3-4 weeks of running.
The moss then spread, taking over even pieces of stone that stayed a little damp.

The java moss shown will do well inside water as well as out.
Once it's settled it takes over the viv.
Not my personal favorite, but i do use it alot inside the tadpole raising tanks since they feed on it.
