In 2012, NEXUS BYT had a production of 'The Wizard of Oz'. One of the major questions was how they would do Oz. After some discussion and pitching I put together a solution, along with Joe Boyle, the live audio/visual producer (http://jbav.com.au/)
The Solution:
1. Make two animated videos (Oz was in two different scenes) that was timed correctly with the dialogue on stage.
2. Display the video on a screen using rear-projection at the correct time of the scenes.
