GoGeometry Action 139!

Creation of this applet was inspired by a problem posted by Antonio Gutierrez (GoGeometry). Feel free to move the LARGE BLUE POINT to adjust the size of the (soon-to-appear) polygon at any time. How would you describe the phenomenon you see in your own words? How can we formally prove what is dynamically illustrated here?
