animation and helmet added by Matteo Rovatti
From this storyboard by Dave Sim. We tweaked a couple of thing: like the butterfly landing on the sword.
I don't know how we can make a sword cut through the butterfly (in real life that would be impossible -and cgi is more "real" than 2D....or so is the thinking of this decision) and then not sure how we would show all the little Butterfly guts:)
