Just in case you missed it, Animation Magazine has a short interview with animator Joan Gratz that is worth reading.
And if you haven't seen it already, head over to the ShortsHD website (www.shortstv.com) where they have a short video interview with Ms. Gratz talking about the 'painting with clay' animation process that she pioneered and used to create her Academy Award winning film "Mona Lisa Descending a Staircase".
On her website: www.gratzfilm.com, Joan has video clips and images of the films and commercials she's produced as well as books and DVDs of her work for sale--including "Mona Lisa Descending a Staircase".
