The Source

An animated short film by Jerzy Kucia, made using means characteristic of his work and consistent with the artist's melancholic poetics. The combination of various techniques, including cut-out and stop-motion animation, and frames bathed in black and white, showing (not entirely) still life, are tied together by the musical composition of Marek Wilczyński, Kucia's several-time collaborator.
