Oh, it is pretty much conceptual (and I hate filth!). The thing I find helpful is, if you build out Versailles in your mind, then you can take the key elements that work, and go with those. What I found liberating about Paulette's caves was that the organic forms don't have to look "naturalistic" to be beautiful.

Exoterra and others make faux rock ledges and planters that stick to the side of the cage (clip with sticky on glass, or strong magnets, and rated for a pound). I love the idea of elevated plants in these, but don't like the faux rock look. These would be very pretty against the clear glass in more free-form off-white sculptures.
