Someone needs to build smart-tiles that we can use to build theater (any any room) ceilings with. You can have it be white and it gets electronically switched to black via the theater startup macro. Think switchable privacy glass
Maybe this can be something that can make use of an automatic pool cover to mask the white ceiling. Already invented but repurposed for something different.
