Aquascaping Help

I just purchased a 90g tank and have a chance to make some changes and want to do it right before i transfer my tank over.  I think that I would like to try to build two towers on each side and then have a few rocks that bridge accross.  I may be asking for too much. 

Thanks, any tricks of the trade are much appreciated.  Are most people gluing their rocks together or are they just stacking them.  I do see a lot of the time where it looks like the rocks lean up against the back glass.  My only concern with doing that is being able to clean around the back of the tank. 

Vadryn that is just what I was going to write.  Drill your rock with a hammer drill or regular drill.  Get some acrlic rod to put in the holes that you drilled.  Its best to do this on a lay out of your tank.  I have seen it done before where they take cardboard and cut it to the size of the tank so they have a good idea how its going to look when they build there rocks.   This is what I plan on doing with my tank here soon.

I think this guy used something similar to ice machine water line, but in a larger diameter like 1/4" or 3/8".  It's kinda flexible and would probably be really usefull if you soaked it in hot water as you were using it to make it that much more pliable.  Ice mache water lien may be just right if you are talking a smaller tank or using smaller peices of LR.

I'm prepping to switch my 90g from FW to my first SW tank. so I'm going through the exact same stuff in my head.  Do you already have your LR or LBTR?

This tank needs some serious love (The corals for it have been taking up half my frag tank), but it has several scorpionfish in it so I am not fond of sticking my hands in the tank. 

Some of the top rocks are touching the back glass.  They are all stacked w/o anything else holding them up/together.
