We're running a few candy crush tournaments for this exhibition (thematically linked) and I would really like to emulate (visually not literally) a mobile screen/project in 3:4 but I'm not sure it's possible without just using actual phones...
I know it's possible to use adapters for both android and ios but we don't have budget and because it's a public event & the tournament is a time trial thing I'd be wary of it not working so well
I actually might just literally set up some cardboard filters/frames for this instead..
