So, perhaps you're suggesting a new piece. Perhaps, even, you've just walked into one unknowing.

Yeah, that's it. Now you've got it. A new piece.

For instance, take that one word "Out." without an exclamation mark, which comprises an entire scene.

What a challenge for the imagination!

It could be any single word, of course. Or something more than a single word.

Where would it go if "the audience" created the settings and the bare bones of each scene whilst the playwright pulls it all together in private.

"The audience" is a co-creator, technically, but the production would be a total surprise to the audience once the play is finally performed.

Another fleeting thought: You don't need to see a play to imagine a play as anyone who has studied plays in academia knows.

This play would give full play to the imagination of the audience before the audience ever sees the play.

That's "the thing" about this play.

Since the play is audience-driven, the audience is sure to love it.

P.S. I have some more ideas which I will PM to you if you are interested, no obligation, of course.

BTW I am not walking into a play "unknowing".

I am walking into a play "unrealized", whilst fully realizing what I am walking into.
