 Conclusion
 ==========
 
-The most important contribution of this article is
+The most important contribution of this article is the simple
+interface between LEGO bricks and an optomechanical computer mouse,
+which alters the economics of creating custom controllers.
+
+There are several positive attributes to our approach:
+prototyping new controllers is cheap, in the region of $30-$100
+per controller. Controllers are easy to build and the parts
+are reusable.
+When using USB mice, it is possible to attach as many controllers
+as desired to a single computer and the controllers are easy
+to use programmatically e.g. in Linux.
+Additionally, this approach is able to tap a hidden resource:
+a considerable fraction of scientists and students actually *do*
+have previous experience with LEGO bricks. And of course,
+building controllers is both fun and motivating.

-Pros:
-
-- cheap 
-- easy to build
-- reusable parts
-- USB -> can attach as many as we want, simple to use
-programmatically e.g. in Linux
-- taps to several scientists' hidden background in LEGO building.
-- fun, motivating
