ZERO: the inside story -- Film Description:
"In this striking and engaging film, Schogt begins a journey to seek the cultural roots of zero. She ponders the origins of its shape—a circle whose emptiness inside is protected from what is outside it—expounds on its usefulness as a placeholder in our counting system and confronts the fear of nothingness."
-- Liz Czach
