Unfortunately, this wasn't fun for the cats, who've been dead for hundreds of years...
Comments on that post at the Athanasius Kircher Society lead to organism, a blog entirely about making art with living systems.
(Giant cockroaches drinking from a bathtub? Or is it all about scale?)
Back at the Kircher blog -- which is touting House Trucks this week -- is an earlier pointer to a proposal reported at Discovery News to weave houses from living trees (for your descendants, I suspect).

The habitat is based on an ancient gardening method known as pleaching, which weaves together tree branches to form living archways, lattices or screens. These huts have been created with pleaching.
Do the trees complain?

Meret Oppenheim. Object. Paris 1936. Fur-covered cup, saucer, and spoon, cup 4 3/8" in diameter; saucer 9 3/8" in diameter; spoon 8" long, overall height 2 7/8".
Thank you Meret Oppenheim, who first showed me as a teenager that some grownups make objects like this and are taken seriously. Only much later did I learn that the surrealist was a woman.
