In Superhuman Flights of Submoronic Fancies, Tanaka reflects on philosophy, religion and morality. Densely colorized images and voiceover shape a complex structure of metaphor and meaning, as religious archetypes and concepts from "the Age of Enlightenment" are juxtaposed with individual stories that pose questions of guilt, lies, and the precarious state of life in an alienated culture. In this often stunning visual collage, Tanaka touches on the history of reasoning and self-definition as she contemplates human existence in a post-nuclear world.
