Original rubberband effect?

I have seen a ton of rubber band material before and have not seen that yet, however it is not very difficult to figure out if you do much magic with rubber bands. From a layman's standpoint (which is all that matters anyway) it does look cool.
 
I believe this is a common rubberband "knot" (if you know what I mean by that) - from my POV that's what it seems like it... from the way it appears.
 
I think I might have seen something similar that Calen Morelli posted on his "365 Days of Magic" though I'm not 100% sure. Anyways, it still looks pretty awesome and I like the idea. :)
