I think a freeform art-house piece presented in Reflectorama would be just the ticket.

Through cutting edge Silveredglass(TM) technology the screen would show a cinema audience astonishingly similar to the one seated watching the piece.

The sounds too would be generated by the audience creating a unique cinematic experience.

What's more, being freeform it could last as long or as short as the exhibitor wished and could be shown in any theatre on a screen of any shape or size making each performance as individual as those viewing it.
