+  Things to do:
+    - remove Lines - NO - they seem harmless enough!
+    - add better "make active" methods
+    - remove the "root node" concept.  Tie nodes to elements better, so we can check if a parent element is root
+
+    - allow progressive exploration
+      - allow easy supplying of an ajax param for loading new kids and a loader anim
+    - allow easy exploration of a ul or ol to find nodes
+    - limit to an area
+    - allow more content (div instead of an a)
+    - test multiple canvases
+    - Hidden children should not be bounded
+    - Layout children in circles
+    - Add/Edit nodes
+    - Resize event
+    - incorporate widths into the forces, so left boundaries push on right boundaries
+
+
+  Make demos:
+    - amazon explore
+    - directgov explore
+    - thesaurus
+    - themes
