A minecon block

Since minecon live is a convention you interact with at home, i wonder " if minecon live is something you watch at home, what about those who want to do special minecon live activities in-game and watch at the same time" well I think we need a special block that shows what's happening at minecon live and allow you to interact with the stream in game via Redstone signals. The block should also double in size when the amount of the block is ×4 it will increase in size allowing theaters to be possible in game. I would really like this to be a thing as minecon live is something you can attend at home and this would allow you to watch in your world or realm and still enjoy the fun. From: afloatactor5068
