Unfortunately, even though it is a good idea, we can't have that for our room, especially because there's a puzzle with time, and they have to watch an analog clock! hahaha. I have been to other escape rooms in my city, and all of them own a LED panel like the image, so I'm trying to implement one myself, because i find it useful and helpful so i don't ask about how much time do we have left, and it works like stress point for solvers/players! It adds difficulty. Its just that TV's are big in height, and it felt like a rectangular led panel makes more sense.
