@Sravis: What you are talking about is actually part of my fascination with herps/amphibians. If you have not already checked out the following sites, I highly recommend them for exactly what you plan on doing:

I would roughly order them like this for the best info on vivarium building:

www.dendroboard.com (poison dart frog community, they ALL build vivs; TONS of info here)
www.vivariumforums.com (the link in the upper left is a redirect to OrchidForums another decent site...to get to the actual vivarium forums forum use the other set of forum links...this site is good but not very active at all; however a fairly good chunk of info is stickied here)
www.chameleonforums.com (most cham owners dont build vivs, but check out the PYGMY CHAMELEON subforum; those particular kind DO need vivs)

Also, I've been building my own vivs for a little while now so feel free to shoot me a PM if you had any questions (or email might get you a faster response
