The gif is a humble thing; an animated icon that's usually used to endlessly repeat the funny clip of the week, and to act as a snazzy avatar to impress all your friends on forums.
But Gus Mantle has decided to put a little more care and attention into creating some gifs, and has elevated it to a mini art form, with this series of incredibly detailed gifs of classic movie moments.
Ranging from obvious movements to the most subtle inflections, there's a whole range of them at his website, but we've picked 15 of the most iconic.
The Full Metal Jacket lads must be getting tired now.
