Background for a tank

[jboone82590]

So me and a friend just got new tanks and we wanna do backgrounds for them.
We want to do tile with sand glued onto it to make it look kind of like a cliff of sorts. We would like to do a few ledges on them but not sure on how to do them or what to make them out of.
I have thought of just gluing little pieces of live rock to it to make little ones but I want some that are a few inches wide and deep to put coral on at different depths. Maybe cut tile and make shelfs or make some out of foam?
What is everyone's thoughts on this and has anyone done this and what did they do if they have?

There's a lot of videos of this on YouTube

I have looked at quite a few about the foam

Why not use shelf rock for the ledges? It will look way better than some square tiles and more natural.

What is shelf rock? Is it real rock?

Something like this. I'm pretty sure it's mostly man made, but it looks real and does the same thing. All the rock in my tank is "real reef rock" which is man made and placed in the ocean to become live. I love it. This picture here, is of "real reef rock" I believe.
