What a cool concept, Kinstrome! I read through your thread and like how your setup turned out.
My tank came with a cork bark background that I would love to utilize. This setup will house a day gecko, so I'm trying to consider what's best for the critter, not for me. I think she'd prefer the added climbing area, especially if I can add some cork rounds to the flat background, like pictured here from NEHerp:
I can attach the background with magnets for easy removal, rather than silicone or glue.
