An aquarium in your household sounds very interested.. Would be the first!
Two mirrors opposite each other in my bathroom run virtually the entire length of the room from the waist to way up high.
At one time I thought I'd install an aquarium in the far brick cavity wall to greet me as I entered and to distract from gazing endlessly at myself in the infinity that the opposing wall mirrors create.
When I can tear myself away, one day I'll put that fish tank in, build the verandah, and play groovy music.
