Self-Intersections in a Polygon

​
The gray figure is generated by coloring the interior of a sequence of vertices forming a self-intersecting polygon. By moving the handles (black disks) this Demonstration allows you to see the self-intersecting points (red disks) thus generated. You can use Alt+Click to create new handles.
