Neon Trees

*The neon-tree emits a little light but it's not the main purpose of the tree.
I thought the trees were a little boring so I came up with this. I know the picture is half-decent. If you have anything better feel free to post.

 

i could see this working especially if you spread them across the surface of the planet

 

I like that very much. In fact I posted pretty much the same idea a few days ago. I didn't have such a nice picture to illustrate it though ^^
