Here was one of the nicest palludarium's I've ever seen a picture of, this was what I was referring to at the meeting and I wanted to share it so that it might inspire some of you to tackle this concept:

I was thinking this type of setup might work for frogs too if it were slightly modified to have a few smooth branches dipping down into the water. I've even seen a few of these that even had discus in them. I think the chameleon is really awesome in that tank above as well. Not to mention that tropical terrestrial plants are readily available and are very cheap additions to this sort of setup.
Niko made a good point at the meeting, that some emergent growth tends to happen in our tanks. I keep amazon swords, and they try to break the surface just about every week. I would imagine they would look amazing if I let them grow to their potential, and I'm sure we could list countless plants that try to do this in our tanks.
