The main goal of this project is to show the Muller Lyer illusion using video and sound: the visual part enhance the experience with the audio illusion while the audio part provide a more concrete experience of the visual part. We animated the "arrows" so that they seem to be shrinking while moving upward. In order to deepen the experience of the illusion, we made a Shepard tone that the pitch of the tone seems to be moving upward forever.
Is this a good/useful/informative piece of content to include in the project? Have your say!
