Mirror Worlds is an audiovisual digital art object by Massimo Magee, designed to be read by the computer as both a visual still image and a piece of audio, these being two readings of the same file. These two readings have here been layered into a movie file for ease of viewing. The piece was shaped across visual and audio domains functionally simultaneously, with a change in the visual also affecting the audio, and a change in the audio also affecting the visual. While the computer sees the file as a hybrid object, having both visual and audio elements enmeshed within and between each other, human observers require separate translations into visual and audio. The piece includes processed image data and virtual guitar generated from the image data. It was all created at Massimo Magee's studio in London, UK.
