Do you think effects with very big angle problems cause the performer to be more creative with how they present an effect or do you think it will only hurt the performance?
One of them is an effect i'm working on right now called....(until i come up with a better name) card through dollar. When doing this no one can be behind me. I think another one is fallen by Daniel Garcia.
Ooh,is that all? Pssh you have no problems there at all. Its the same old thing magicians deal with in any/many tricks.
Your audience should always be facing you anyways so why would they be behind you? Its all about audience management and knowing how to pick your crowd. Obviously not for all tricks your going to want to perform for 6 or more people. Same thing for fallen.Though personally I wouldnt perform fallen as I dont find it very interesting.
