Platypus Multimedia Author - Version 3.0 Platypus Multimedia Author is a lightning fast, fully visual Multimedia authoring system. The great thing about Platypus is that you edit live, executing applications through the unique True Interactive Editing (TIE) technology, which joins and supports different media - a leap above the traditional WYSIWYG. This new technology is, as described by 10-year old Diana, “heaps cool”. All major media file formats are supported.
