Shelldrake Developer - Version 1.8.1 Shelldrake Developer is a multimedia authoring and animation program. Its "story- first" authoring paradigm aims to put the entire creative process in the hands of the storyteller, the teacher, game designer, scriptwriter . . . the person who has something to say. Shelldrake’s automatic speaking animation puts realistic conversation and with it, realistic human simulations directly within the reach of the author.
