I posted this on another forum but figured I would share it here for anyone interested. Although it wasn't for a frog tank (Lygodactylus williamsi), I had some cork laying around and tried to see what I could do with it. I started with a Perfecto 37 gallon column tank, 20"x18"x24" and used over 50 pieces of cork bark, plus foam and silicone, to recreate a tree trunk. I blacked out the back of this tank from the outside, and left the sides open to make this tank viewable from 3 sides on my coffee table.
First I joined a few pieces to make them look like tree roots, right here there are about 20 pieces of cork bark.
Then I collected some tree roots to use as branches and sterilized them in the oven.
..and some of the inhabitants:
male
eggs
newly hatched young
