30 Day Fictional Settings Challenge, Day 17: Stage/Musical Sets

There is a real art to creating environments within the spatial and rotational constraints of a stage production. Whether electively skewing towards the minimalist end of the spectrum, or filling the stage with as much opulent detail as possible, there is a long history of inventive design to pull from. What is your favorite example of a scene or setting from a play or musical that you have seen on stage?

Bonus: Have you ever been part of a production? Any scene-related highlights from being onstage or backstage yourself?

Adaptation Bonus: What stage production has been most successfully translated to the screen?
