Gradation of Happiness

Gradation of Happiness is a series of graphic artwork showcased on a newer (but still defunct) version of the OSD website. It's unknown whether every work in the series is showcased here, but it's possible seeing that some of the other sections (Anonymous Animals) are not complete.

This page is the only known reference to the series, and source of the artwork.

Trivia

Sato can be seen editing one of these images at approximately 2:35 in the Next Beat interview.
