Another property of Marco Rocks that make it very attractive is the "lacey" texture to it. There are many pieces in my collection that have holes that you can literally see through a solid 1/2 foot of rock. This makes it incredibly easy to aquascape.
You can simply put acrylic rods, zip ties, or any other material through the stuff to create incredible displays. As a matter of fact, I'm pretty sure (Marc can chime in here or..I will after going to see the site again) that Marc has a presentation of sorts on his site Home that shows how you can use various methods for building the rockwork.
