What is the smallest space?

A little free library inspired platform in front of our house where instead of giving out books there is an expanding collection of rotating little art projects or displays. These projects or displays provide amusement for me in the making and ideally a tiny bit of amusement for somebody walking by.

The smallest space may go away entirely for long periods of time, but my goal is to generally rotate out different little projects at least a few times a year.

Currently outside: marionette house

The current project is the marionette house, a simplified stand-in model of our house with light switches that actually work.
