Show me some decorative enclosures please

[eggcellent]

Hello all,
I see a ton of naturalistic enclosures on here, however, I am wondering if anyone has done some decorative kinds?
I own a lot of inverts and I feel their enclosures are plain in comparison to my snake's enclosure. I only got one response on a facebook group that had some amazing pictures in it, including one luck green bottle T whose enclosure had a bunch of alcohol bottles in it.

Additionally, is there a list of products to avoid putting in invert enclosures?
I know copper is a definite no no, but are there other plants/products or even types of wood to avoid?
Thanks to anyone who can provide some neat pics

I've never used Cu. Why is Cu bad? Is it a known toxin of arthropods in heavy amounts?

This is the most "decorative" enclosure I have so far. My GBB enclosures have a lot of color, but it's just aquarium silk plants, and I don't think that's what you're talking about.

Aaaand one more because she's cute

It's pretty simple, but the tea cup reminds me a little of Alice in Wonderland.

Thank you for asking that question. I've heard about Cu being bad but I never understood why.

Edit: Oh, wait , I think I remember an article about roaches I read once (possibly provided by @Theneil ?) where they showed that Cu was bad - but you had to feed copious amouts to the roaches for the bad things to happen. Unfortunately I can't remember the details - my memory is going, Alzheimers, help!!!
