The Sundance Channel continues its partnership with Isabella Rossellini, who wrote, directed and stars in in a series of quirky films entitled "Mammas Day" for Mother's Day. The films, which will be broadcast on Sundance on Sunday evening, feature the actress playing the parts of different kinds of mothers from nature, including a wasp and a cuckoo. (Rossellini's previous collaboration with Sundance was a nature-themed series of movies called Green Porno). To create a Mother's Day card with the movies, Sundance and production company Tool have created an HTML-5 website, where you can choose a suitable "type" of mother, and send the corresponding video as an e-card.
