We like this look so much that we're going to make an aquarium box the same way (but obviously without bars), and I also think this would be a good look for a "forest" box- with trees etched onto glass and maybe woodburned onto two wood sides. We'll see if this pans out.
And right now my parrot is being SUCH a sweet girl- a rarity. She's rubbing her head underneath my chin and cooing to me. Perhaps we'll do a parrot box, too.
