New York Theater Workshop Is Transformed for a Show

Ivo van Hove and Jan Versweyveld discuss with the NY Times their design for Scenes From a Marriage.  

Just wondering if you ever came across a set with a waterfall with running water? Our set designer was talking about possibly doing one and i tried to do some research but found almost nothing. I was just wondering if you've seen it done on another stage?

Are we talking gushing Niagara Falls or a waterfall feature in my office?

Anyone able to help?
