Orchids terrarium

I would like to know if there is anyone that is part of this fourm that has photos of their orchids in a Terrarium?

I am thinking of building one for my wife birthday and I need some ideals.

So, are there any photos, examples, suggestions or detail plans that anyone would like to share with not only me but the rest of the fourm?

Lots of Orchids don't need a terrarium.  Could you give us an idea of how space you have, max amount of money your willing to spend, ect.
