“Zimmer Twins” is a website designed mainly for children because of the infantile, funny characters it has, even though it can be used by older users who want to produce creative storytelling through short clips: cartoon movies. The site offers as little as three characters: Edgar, Eva and their cat, whose name is 13. One may think that three characters are not enough, but the range of activities, emotions, props and backgrounds is so vast that those three characters will end up being more than enough. This site is an authentic one, since “the tasks and activities students do and the people they communicate with to do them are real and motivating (Peachey, 2010).”
