Ahh.. I can't remember which forum it was, but there was a person who was using great stuff to coat the inside of a large bookcase, which he had converted to a large display cage. He was coating the walls (and some branches that he had attached), to make a bumpy, almost viney texture all on 3 walls of the cage, building it out bit by bit as the stuff dried. I didn't see finished photos, but it looked really cool from the stages I saw. I believe he was going to paint parts of it, and glue moss to other parts, and that an arboreal snake was going to go in it.
Arg! Well, I'll post a link if I find it.
