proximityAnim.mel 1.2.0 for Maya (maya script)

I'm trying to animate the visibility of several polygons, like in your example video. However, I am unable to get the operation to function. I have several faces from a simple object separated out to polys. History is cleared, etc. I run the script, select all the polys, add them, select visibility and the apply the script. After placing the Location node, adjusting the control distance and animating it I get no results. I've tried starting the polys with visibility turned off and on. What steps did you use to create that effect and where might I be doing it wrong? Thank you very much!
