Muto: An Ambiguous Animation Painted on Public Walls
Blu has created one of the most incredible stop-motion animations I've seen. Painted on walls in Buenos Aires and Baden over this past winter, the piece features a black-and-white creature that morphs into various blobby forms.
Starting off as a multi-armed monster, it constantly shifts with the most consistent tropes involving head changes—from spiky to cubed to round, etc. and sometimes devouring/birthing itself. There's also plenty of other mind-bending evolutions involving things like crawling teeth and creepy bugs. It gets even better when the creature(s) interact with the surrounding details, crawling into corners and snatching pieces of paper off the wall with a frog-like tongue.
