This is an incredible little cgi short made mostly by a single artist Ian Hubert in blender over a several years. It's amazingly detailed and does a really go job of using a few actors and live green screen elements shot on a small stage with these intricate and amazing scifi environments. The guy does a lot of tutorials and behind the scenes stuff on how it was made and it's a very impressive piece of work especially so since it looks better than some productions with huge numbers of artist.
