 By far the most difficult part of 
 
+- zeroth solution using hand-made cardboard optomechanical discs
+    
+    - bad idea
+
 - the first solution using only small LEGO cogwheels
+
+    - easier to construct, still too easily hopping over 
+
 - the second solution using non-LEGO cogwheels
+
+    - ???
+
 - so far final solution using mouse's own grid wheel
   and LEGO tires
 
+    - easy to construct, reliable
+
+    - best part = 132-old, but the shaped tyres will also do

 An example custom controller for a particular user interface

 Pros:
-- cheapness, 
+- cheap 
 - easy to build
 - reusable parts
-- fun
 - USB -> can attach as many as we want, simple to use
   programmatically e.g. in Linux
+- taps to several computer scientists' hidden background in LEGO building.
+- fun
  
 Cons:
 
-- shape edged, unconformtable
+- shape edged, uncomfortable
+
     - several options for design
+
        - slopes + inverse slopes octagon
+
        - rounded bricks
+
        - wedges
+
     - more ergonomic handles could be made by covering
       LEGO handles with modelling "pasta" / paste / something
 
 - weak (legos may break apart)
+
     - requires careful construction

+       - see tips section

     - gluing parts
 
+- mechanical looseness
+
+    - some inevitable
+    - humans used to some

+    - can be alleviated to a great degree by careful construction

 - requires calibration

-Some solutions for cons:
+- having to explain to budget counters purchases of LEGO sets with
+  interesting names (or bricklink purchases)
