The first thing would make some great hanging gardens or perhaps a bird feeder. The material kinda reminds me of a nest. The water containers, other than well containing water could be used for a great way to make bio-ferments while safely storing seeds. Here's some notes I took on how that system works. It stacks functions by cleaning seed while making bio-ferments of your choosing.

Hope it's understandable. You'll need to seal your pipes in there somehow, but also figure out how to detach them to take out your seed or harvest that needs cleaning from pests and such.
