Aquascape Ideas

I've got a custom 97 gallon tank on the way (it's roughly rectangular,
footprint is a bit larger than a 90, with a largish overflow in one
corner. The tank will be visible from 2.5 sides (front, right end, half
of the back) with the rest being visible only in the laundry room where
the sump, refugium and related equipment are are set up and waiting.

I plan to buy 250 lbs of live rock from Tampa Bay Sal****er (I want
aquacultured rock, and "The Package" is a nice price) for it.

My current plans are to aquascape it with an L against the left side and
the part of the back that isn't exposed, and to have a cave in that L
somewhere, and a mount on the right side of the tank. Any ideas on how
to go about this, or exactly how to lay out the aquascape? Where and
how to put the cave, etc?

Thanks,
Eric
