It's Snow -- Film Description:
"Colour cut-out animation inspired by the shape of snowflakes and touched with the airy magic of these fragile designs. While music tinkles invitingly, snowflakes roll and whirl, pulse and glitter, shining with the many hues of twinkling lights. Made without words, this is a joyous film to please the fancy and captivate eye and ear."
