i've been scheming for a while to make a habitat out of some screen material...like the stuff in your screen door. i figure i could build a huge habitat that is still easy to view from the font for a fraction of the cost of buying a aquarium, and i would still be able to see my herps just as well! I think this kind of setup would also improve ventilation, it would be really easy to mount lights and things like that wherever you want (cuz you could just build it right into your frame or whatever). not sure if this has ever been tried for private use, not sure why not. I got the idea from my work, we have a diamondback rattlesnake, so as a safety precaution we have him in a room that is completely sealed with that mesh over every opening so that if he ever got out of his tank he would still be trapped in the room.
