The performance, as demonstrated on the DVD, the illusion can be viewed in the round, 360 degrees!
Having said that there are performance angles and there are mechanical angles. If super close-up
and in the wrong light something could be revealed. One of my regular venues utilizes a large
projection screen, I used only one spectator which made the mechanical angle thing non existent. On
the large screen it looked incredible, even with extreme HD close-ups. Needless to say it played
very well...especially if combined with a couple of other well known effects that Penguin offers.
Nice quality, durable and very practically usable.
