Parody of a song "Algorithmic march (アルゴリズムこうしん)" by Masaki Kurihara (music), Masahiko Sato and Masumi Naito (lyrics).
This, as well as the French version, is my earliest animation created with old "Pencil" software in June of 2011 (all the later works are created with Synfig). It is very unskillful from many points of view, but I could not help creating it when I witnessed the worst measures taken by Japanese government against the catastrophe of Fukushima in 2011. It is regrettable that the worst measures are still ongoing.
After I uploaded it on Youtube, decades (or maybe hundreds?) of people followed this penguin parade in their real life. That fact was impressive.
