Hey, I always thought about that. I think it would take a much larger enclosure than a regular sized 4ft x 2ft x 2ft to make a nice display.
I think mulch could be used and a large tree half with a nice hole in the center could be a nice hide or a few smooth slate rocks with nicely sanded edges, glued togther with silicone would work as a dry hide.
for a humid hide you'd have to get ur imagination goin. I'd take a nice sized tub and put a hole in it and grab alot of dried (really dry) leaves. Lots of silicone and silicone them together to make it look like a leaf pile. Go to the store and at fall color leaves (red, yellows oranges) to go with your blood the motif
of the room.
Then you can put straight tree branches, maybe 2 or three that are vertical and about 3 or 4 inches thick. They will be cut on bothe sides str8 and then placed so that they fit perfectly to the bottom and top of the tank with a little tension. These will serve or look like trees.
I'm pretty sure this is what I'm going for in my bedroom as the same thing will be happening to my room. My bloods will be the Motif of my room.
In order to do something like this you'd have to think of the size the snake is or can get. all these decorations in a 4ft x 2ft x 2ft would definatly leave ur snake with no room. But just imagine a blood in a type of setup like this who has some awsome red and yellow coloration.........WHOA!

Hope this helps,
