Hey thats the same size enclosure I just built. I'll post a pic later tonight of it. I have a crested gecko in there now and plan on getting a couple more to put in there. I have some pothos and philodendron in there that seem to be doing very well with a thirty watt flourescent light. There are quite a few options for both animal and plants. Take a look in the natural vivarium forum there are some good threads there.
It's not that I'm lazy; it's that I just don't care.
