What do I do with my old vivarium

I currently have an Exo-Terra 18x18x18 glass terrarium:

I am getting a custom made tub/rack from Snake Shacks:

I have no idea what I am going to do with my old setup.

Any Ideas?

Considering that those cages were probably intended for some kind of arboreal gecko or frog in the first place, I'd go with one of those types of animals. A trio of Tokay geckos would be wicked in a cage like that....

Or cresties! Who doesn't love cresties?? :P
