It won at least two creative awards: Certificate of Appreciation (Top Category) and Oberhausen Mention at the Festival of Youth Paris.  The film was also shown in several schools by invitation.  The film was directed by John Krish, written by Krish and Michael Gilmour, and produced by James Ritchie.
