Theatre: how to present performing which is two or more activities acting at the same time but different time or space? ?

 

In theatre, a scene which is two issues happen in the same time but different locations or same location but different time is familiar, therefore, I want to do some textings about showing more than one 3 dimension on the stage at the same time. For example, how to present performing which is two or more activities acting at the same time but different time or space?

Currently, I took some photos at the same location and different time in one day, then combined them as one. Through this photo could you feel time existing (or time pasting)? Could you see a set of activities happen at the same time? Or various emotions involved? This practice is inspired by David Hochney's arr works, stage design. His design, like Die Frau Ohne Schatten and Magic Flute, one play has more than twenty different scenes combining different set of lighting to issue story, which greatly impressed me.

Since my research is about communication of digital media in theatre which is difficult for traditional theatre to achieve. I am thinking, what kind of skills (like projection?) could achieve that live acting ? Must well combine with the live play's setting? And what else? Will audience still feel like watching a feel but play?
