This post is from one of several previous incarnations of this site and probably doesn’t quite fit the current format. In a former life this was a group blog and a tumblelog before it became a static jekyll site. If anything looks broken or is worded oddly that could be why. Pardon the dust.
H.G. Wells’ short treatise on the construction of building block dioramas for the purpose of being at play in imaginary worlds. See also his follow-up volume “Little Wars” on enacting war games in same.
