Interesting thoughts. So you're talking more like when the audience doesn't even know they're seeing a magic performance at first? As in the Carbonaro Effect? I know Derren Brown had a whole section of his career where that's essentially what he was doing with Hero at 30,000 Feet, Apocalypse, etc, and some bizarre magicians/seance artists have been doing this for some time now. Some of the material in Garden of Strange or Art Vanderlay's 'Elemental Manipulation' work would fall into this immersive category too.
