Revisiting this thread. I never got to see it when it had pics, I'm a bit bummed that photobucket broke it. I was a about to create a thread as I've been wanting to make some of these for years.
I see people discussing floral foam in regards to these all the time...but looking at stills of the one polyhedron that gets crushed, did anyone ever notice that he's careful to crush it on the bottom? It almost looks like the styrofoam is filled with something like fine sand. Look how much is coming out in this shot::
It seems like an awful lot for the little bit of the polyhedron that he crushes, doesn't it? What do you guys think?
