+## Synthetic maps
+
+For tests and tutorial mode, I totally need the ability to create little
+synthetic maps in a UI. Should be different than the main UI.
+
+What are the 'abstract' objects to manipulate?
+
+- Intersections... just points
+	- Move these, have the roads move too
+- Ability to connect two intersections with a straight line road
+	- Edit lane type list in each direction
+	- This lets border nodes be created
+- Place rectangular buildings
+
+This should basically use raw_data as primitives... or actually, no. GPS would
+be weird to work with, and roads should be expressed as the two intersections,
+so we don't have to update coordinates when we move intersections.
+
+How to map lanes to stuff that make/lanes.rs will like? Might actually be easy,
+actually.
+
+Ideally, would render the abstract thing in one pane, and live-convert to the
+full map and display it with the editor code in the other pane. But as the
+halloween experiment shows -- that'd require a fair bit more refactoring first.
