-*Break lines* are a technique used in technical drawing 
+Break lines are another one of Fenfire's user interface techniques
+that have been influenced by technical drawing.
+In technical drawing, break lines are used
 for indicating
 where an object extends beyond what is drawn in the current
 diagram. It is visually clear since it uses a shape that
 is obviously not a part of the object's own shape
 (wiggly freehand line, see Fig. [ref-fignasa]_).
 We apply this technique by drawing the buoys as 
-non-photorealistical pieces torn off the target document.

-For example, animating a fragment to a full document
+An important part of the design of break lines in Fenfire
+is the fluid animation:
+for example, animating a fragment to a full document
 should not look like the edge just gliding
 over the document, but rather as if larger and 
 larger parts were magically torn off the original document. 
+In the software engineering part of the Fenfire project, we have
+just accepted that this type of animation
+seems to work and moved on; however, this has opened a number of
+interesting questions for basic research.
