I went out and bought the white portland today. I actually went to the place where they bag it up and checked out the facility a little bit. Its pretty sweet but uber dusty. I thought my job was dusty but that puts mine to shame. Any ways to make a long story short, I've got the white and grey in the mold, I built in a cave with a tunnel system. Its goin to be marbled. Its got a montipora skeleton style shelf built in too. It should be ready tomorrow about 5 but I'm going to let it sit untill tomorrow night when I get off. I will have pictures up in the next few days
