A friend and I were comparing our stats after a match, switching back and forth between our two profiles when we noticed that the little box in the bottom right corner that showed what weapon we got the most kills with could be turned into a nice little animation by switching back and forth rapidly. I had the most melee kills so mine had an arm, and he had the most with the battle rifle, so it was a gun with a long slender tip, that conveniently looks much like a finger. The video speaks for itself:
