Not to quickly change the subject... well yes, to quickly change the subject... Here's another really nice cage design with plans for how to make it (
Striking Serpents/Boa & Python Photo Gallery). I bet if Hilde's incredible design and these brilliant plans were merged, it would make an awesome vivarium. One might need to add a "door skirt" between the two sliding panes of glass to make it escape proof for garters.
