In Design: what can I use for this effect

[crystalview]

I can not identify the wood or rock on the back wall in the link below. I would like to find away to mount moss or nana anbias up on the wall, without taking up a lot of space. Have any other Idea's on how I could do this and get a shelf look?

I like the look in the pictures at the bottom, when they are not grown in so much. In "Tank" it says's its roots could that be right?

I know you can use a sort of cork that would work well. It should be readily available but I guess organic so no chemicals in it....

You can either cover the whole back, or cut/glue smaller sections or a top border as you like.

I like the looks of the tanks as well. Very nice.

You are very right about the cork. I saw Tom's wood collection today and he has perfect strips of raw cork that would look cool and not take up much room. I forgot about raw all I could picture was the panels we used in the 60's to sound proof or some did hole wall with mirrors strips in between.
