This short was put together by Nicolas Leandro Montes on a minimal budget.
I’m not savvy enough to know for sure, but the technique looks like some sort of rotoscoping. That’s the animation and filming style Ralph Bakshi used in the 70s Lord of the Rings animation.
Montes’s movie is The Black Tome of Alsophocus. The Black Tome is based a short written by Lovecraft, published after his death and never finished.
The extension was done by Martin S. Warnes, completing the story with the unwelcome addition of Nyarlathotep.
