The artist Masayo Fukuda has been practicing the art of Kirie (切り絵 - literally ‘cut picture’, the Japanese art of paper-cutting - for 25 years. This amazing octopus is (from her own words) her greatest masterpiece of 2018. 

Although the intricate piece looks like several layers overlapped, Fukuda stayed true to the conventional form, using only a single sheet of paper to render her detailed depiction of an octopus [source]. 

This is truly beautiful. Look at the level of details !
