Why not just use projectors or LED tiles to change the game being played? Seems like mechanical engineering is a bad abstraction for this problem.

> Why not just use projectors or LED tiles to change the game being played? Use projectors or LED tiles to do what? The problem is American football is played on artificial grass, and Association football is played on real grass. No amount of projectors or LED tiles will switch between those two, will they? > Seems like mechanical engineering is a bad abstraction for this problem. How do you change artificial grass to real grass without any mechanics?

  Wasnt aware of that distinction, thought it was just shifting the markings. In that case it does seem like mechanical engineering is the only way.

  ”The problem is American football is played on artificial grass, and Association football is played on real grass.” Not necessarily. https://en.m.wikipedia.org/wiki/List_of_current_National_Football_League_stadiums#List_of_current_stadiums https://en.m.wikipedia.org/wiki/List_of_current_National_Foo... shows about half of current NFL stadiums use natural grass or hybrid surfaces. Also, association football is played on artificial surfaces, but not, I think, in the Premier League. Tottenham seems to play on a hybrid surface, though (http://www.dessosports.com/sports/football/football-projects/tottenham-hotspur-whl-stadium-uk http://www.dessosports.com/sports/football/football-projects...) A big reason to have multiple surfaces is that one wants to use the stadium frequently. A NFL match would cause too much wear and tear on a grass surface to have a quality surface for a soccer match a week later, for example. It also takes weeks to remove the NFL logo from a natural surface.

    > Not necessarily. I didn't say it was necessary. I said that's what they're doing. At this stadium they play Association football on grass, and American football on artificial. If they want to swap between them then they need a mechanical system to do so.
