Quoted from JimFNB:

Yeah, I'd really love to hear the story behind the topper from Dennis Nordman or someone who was there. I can't think of another machine where this done, so how did they even figure out to use stamped foil, where did they make it, how many prototypes did they go through, etc. I've looked but haven't found this in depth anywhere online. There are loads of stories out there, though, about remaking the topper and then they just fade away after giving up.
