<late speculation> which combines geometric illustrations is a work of co-production by Takami Nakamoto who conducts space and sound works and Noemi Schipfer who does kinetic works. This work is an audiovisual installation which is the first artwork jointly made in Nonotak studio, and receives the greatest review. Work factors which visualize wide musical panorama and brief choreography fascinate audience as they are projected to the surface made into multilayers of a triangle structure on a stage.
