-- Take a [[model of the world]], call it [[m]]. It is embedded in [[protopoi]] space.
+- a [[thought experiment]].
+  - [[shorthand]] for a [[framework]] for world building.
+    - I want to experiment with this in the [[agora]].
+  - Take a [[model of the world]], call it [[m]]. It is a point in high dimensional [[protopoi]] space.
   - The model [[m prime]] results from applying well-defined transforms, alterations, procedures over [[m]].
     - These transformations, in order, are said to form a [[path]] between [[m]] and [[m prime]].
     - More than one path might link [[m]] and [[m prime]]. Intermediate steps are valid models.
