Skull Gif-iti by INSA
INSA is a fine artist and designer who creates real-life gifs! He has labeled them as Gif-iti and each mural is painted and then photographed in sequence to create the animation (of up tom 8 layers) which you can see here. I found this amazing work on This Is Coloassal, and you can visit the post which has a few more executions of the same idea. They are all brilliant!
