Let's try this again: rock wall

In addition to just your average aquascape I want to add a little more interest to my tank... I want to have the scape go up the right-hand side wall, creating a wall of rock caves and cliffs, going all the way up to the top of the water.

I tried another thread on this before, but I guess I could never fully explain myself. I did not know exactly what I was looking for. This time, I have some requirements

-I will have a lid on the tank to keep from fish jumping out.
-The top rock will have to be hung from an eggcrate frame(or at least I would like it to be...) I can use zip ties/acyrlic rods to hold rock together after drilling holes. But I guess my main question is...

How can I hang the rock and still have a lid over the tank?

I've only seen this done once before, so good luck! It was at a fish store in Columbus, OH. But the tank it was a floor to ceiling setup.

Suggestions & comments welcome. Thanks!

 

Can't you do an eggcrate lid and cut out the section where the rock comes out of the tank?

Well I plan on using a glass lid. But instead of using 1 48" I could use a 36" & have 12" of eggcrate..

 

This looks interesting though not quite the look I am going for...

EDIT: I kind of want like what's on the right side of this pic, below, but with more overhang.

I'm not sure if this is what you had in mind or not but it might give you some ideas.

Found it here at 3reef

 

If the rock isn't too heavy you could use square acrylic rods and make a cover from bird netting or clean screen material.

 

This is getting closer! Though I don't want foam; I will use dry and live rock. I love the idea of hiding all equipment.

 

I was thinking of maybe drilling holes in bottoms and tops of rocks being stacked and putting in acrylic rods to prevent things from falling. I want to be able to disassemble things in the future if I need to, which is why I won't be using silicone/epoxy. I will probably go with a glass lid/eggcrate combo for the cover. I think I will draw a pic tomorrow to further explain what I am looking for.
