vivarium project

according to vivaria projects.com to create the beautiful natural landscape below they used peat bricks.

i dont think i've ever seen peat bricks for sale around here but i'm sure i can order them online. i suppose i could just make it all out of expanded foam and carve it to my liking. i wont know the how much water i can put in it until i get it. so i shouldn't try to make a cardboard and foam model like i did for the mountain idea.
