The Savannah Project by Price Street Projects in Savannah, Georgia, USA.
As a port city, Savannah has an abundance of obsolete shipping containers. Artist Julio Garcia repurposed two of these containers to create his residence and studio in the Savannah woods.
By Aki Inomata, quite literally taking the hermit crabs ability for carrying their home on their back, the Japanese artist crafts architecturally inspired shells from plastic for the crabs, with miniature cities on them. I think another fantastic aspect is the transparency, how you can see the anatomy of the crab even when they withdraw is just fascinating.
